Foreign bodies of the urinary tract in children: Multicenter study

Introduction. Urinary obstructions caused by foreign bodies (FB) represent quite a rare clinical case in practicе of pediatric urologists. However, some recent publications note a tendency towards higher occurrence of FB in urinary tracts in children. Most publications on FB urinary obstructions in children are devoted to the descriptions of individual medical cases. Considering the lack of multicenter research works on the problem, a study based on generalized clinical experience of several hospitals appears relevant. Materials and methods. The study is based on retrospective analysis of treatment results of 44 pediatric cases from 10 clinics of Russia and Belarus during the period from 2000 through 2020. The study population comprised 28 (63.3%) boys and 16 (36.4%) girls. Mean age of the patients was 10.9±3.7 years. The children were subdivided into two groups: group I included 28 (63.3%) cases where FB had been introduced in the urethra or bladder by the child; group II included 16 (36.4%) cases where foreign bodies ended up in urinary tracts as a result of instrumental or surgical procedures. Results. Clinical manifestation of FB was typical among the patients in the group I while in group II the condition more often occurred inapparently. Children often concealed FB introduction in the urinary tracts, and so contacts with a healthcare institution were ordinarily triggered by changes in urine analysis findings. Concealment of FB introduction in the urinary tracts determined help seeking start later than 7 days following the incident in 64.2% cases of group I. More than a half of the FB in children of group I were revealed within the first month after the incident. In group II, FB were revealed accidentally during follow-up examinations in 75% of the children. Transurethral FB extraction succeeded in 50% of the patients in group I. In group II, transurethral FB extraction was performed in 5 (31.3%) children. In 2 cases (12.5%), FB were extracted using flexible ureteroscopy. Percutaneous nephroscopy was used in 2 (12.5%) patients. 5 (31.3%) cases required pyelotomy with laparoscopic access, and in 2 (12.5%) patients a lumbotomy had to be carried out. Discussion. The rarity of FB of the urinary tract in the practice of a pediatric urologist is the reason for the combination ofthe existing experience in providing medical care to children from 11 centers. Delayed demand for medical care was noted if FB were introduced by the child independently. The generalized material shows that in childhood, the same approaches to FB extraction are applicable as in adult patients; endoscopic FB removal is optimal. Conclusions. In most cases of children suffering from foreign bodies in urinary tracts, the FB can be extracted using endoscopy without complications and with favourable outcome.

Practical Recommendations

The objective: to evaluate the effectiveness of the proposed therapy in pregnant women with asymptomatic bacteriuria. Materials and methods. All patients were divided into two groups. І group – 38 patients received the course of amoxicillin with clavulanic acid 625 mg per os twice a day for 7 days, group II – 33 patients received D-mannose (1.2 g), powder of 5.8 g in a sachet 2 times a day for 7 days. Diagnostic criteria for asymptomatic bacteriuria were based on practical recommendations of the American Society of Infectious Diseases. Results. In the first cultural research of the urine specimen (immediately after the end of the course of therapy), the percentage of microorganism’s persistence in the urinary tract of a woman was determined, in case of its detection, an additional course of treatment was prescribed. In the second and subsequent control urine samples, the percentage of relapsing bacteriuria was determined. Percentage of the persistence of the pathogen in the urinary tract among the treated women with bacteriuria remained rather low – 10.5% (4 patients) in group I, but higher than in group II 3.1% (1 patient). The percentage of sterile first urine sample was high and probably did not differ between groups – 31 (81.6%) and 32 (96.9%) women respectively in I and II groups. In the first group, the percentage of relapses during gestation after the diagnosed and treated bacteriuria remained rather high and amounted to 23.7% (9 patients), and in the second group, the relapse was not recorded. Conclusions. The 7-day course of therapy with the D-mannose drug is associated with fewer cases of persistent pathogenic pathogens in urine, no recurrence of bacterial infection, and no side effects. Key words: asymptomatic bacteriuria, D-mannose, urinary tract, pregnancy.

Urinary incontinence during sexual intercourse refers to overactive bladder (OAB) syndrome and it is divided in incontinence during penetration and during orgasm. 480 women with low urinary tract symptoms (LUTS) were divided in a) affected by probable genuine stress incontinence, b) probable Urge-stress incontinence, c) probable Urge Incontinence, to specify incidence. Materials and Methods In Group C (186 women) 36 women, age range 24 to 56 years, with urinary incontinence only during sexual intercourse, were selected: 16 during orgasm (group I), 20 during penetration (group II). These patients filled in specific validated questionnaires (ICI-9), urinary recordings and, after urine exam, they underwent US study of urinary tract with post-micturition evaluation. The patients with other urological diseases or pelvic prolapse in stage II of POP-Q or higher were excluded. Patients were referred to physiatric evaluation and urodynamic exam with cystomanometry and perineal EMG, with provocative tests and after pressure-flow study. Results Cystocele was found in 4 out of 16 women in Group I, and in 6 out of 20 in Group II. No patients showed basic detrusor hyperactivity during cystomanometry. In Group I: 50% had detrusor hyperactivity and 18.75% had prolonged perineal relaxation. In Group II 30% had detrusor hyperactivity and 35% had prolonged perineal deficit. Results suggest parasympathetic deficiency in Group I and sympathetic deficiency in Group II.

Objectives: to determine the causes of ineffective observation and poor prognosis in patients undergoing ADHF, in real clinical practice and to consider the basics of the formation of specialized medical care for patients with heart failure (HF).Materials and methods: the study was conducted based on the City Center for the treatment of heart failure (center HF), N. Novgorod. The study consistently included 942 patients with heart failure (HF) at the age of 18 years and older who underwent ADHF and received inpatient treatment in center HF between March 4, 2016 and March 3, 2017. Based on the decisions of patients to continue outpatient monitoring in center HF, two groups of patients were distinguished: patients who continued to be monitored in center HF (group I, n = 510) and patients who continued to be monitored in outpatient clinics at the place of residence (group II, n = 432). The assessment of adherence to treatment, overall mortality, survival and re-admission to a depth of two years of observation was carried out. Statistical data processing was performed using Statistica 7.0 for Windows and the software package R.Results: all patients in the study groups had high comorbidity. Group 2 patients turned out to be statistically significantly older, more often had III functional class (FC) HF, lower the baseline test score of 6-minute walk, and higher the baseline clinical assessment scale. After 2 years of follow-up in group II, there was a significant deterioration in adherence to basic therapy of HF compared with group I. According to the results of multifactorial proportional risk Cox models, it was shown that observation of patients in the group 1 is an independent factor increasing the risk of overall mortality by 2.8 times by the end of the second year of observation. Survival after two years of follow-up was: in group I — 89.8 %, and in group II — 70.1 % of patients (OR = 0.3, 95 % CI 0.2 – 0.4; p1/2 < 0.001). After two years of follow-up, the proportion of re-hospitalized patients in group II was greater (78.0 % of patients) versus group 1 (50.6 % of patients, OR = 3.5, 95 % CI 2.6 – 4.6; p1/2 <0.001). The independent risk of re-hospitalization according to multinominal logit regression was 3.4 times higher in group II and 2.4 times for III – IV FC HF. Conclusions: the inclusion of patients with HF in the system of specialized medical care improves adherence to treatment, prognosis of life and reduces the risk of repeated hospitalizations. Patients of an older age and with an initially greater clinical severity refused specialized supervision in center HF.

Objectives: The classical renal manifestations of primary hyperparathyroidism (PHPT) are nephrolithiasis and nephrocalcinosis. The presence of renal stone categorizes PHPT as symptomatic variant. The clinical profile of PHPT has changed in past few decades with decreased prevalence of renal stone disease with the introduction of widespread routine biochemical screening in normal subjects. In developing countries, PHPT is still a late diagnosed disorder and most of the patients are symptomatic at presentation. Presence of renal stone in PHPT patients is an absolute indication of parathyroidectomy, hence it is important to identify renal involvement in PHPT. The objective of the study is to determine the rate of renal manifestations in patients of biochemically primary hyperparathyroidism and compared to control group. This retrospective review was performed to determine whether the rate of nephrolithiasis and nephrocalcinosis is still high in the patients who underwent dual phase 99mTc sestamibi scan for PHPT at National Institute of Nuclear Medicine and Allied Sciences (NINMAS) compared to those not affected by the disorder.Patients and Methods: A total 149 patients (male 72 and female 77) and mean age 41 ± 14.73 years with PHPT were included in this study. All patients underwent dual phase 99mTc sestamibi parathyroid scan. Result of 99mTc sestamibi scan were divided into two groups. Group I represented positive scan and group II indicated negative scan respectively.Relevant clinical history, biochemical values including serum calcium level, serum parathormone (PTH) level and data on renal manifestations were recorded. The control group comprised of 650 subjects who had abdominal ultrasonography for various clinical conditions without any history of PHPT. Renal manifestations were compared between PHPT patients and the control group.Results: Among 149 patients, scan was positive in 54(36.2%) cases (group I) and scan was negative in 95(63.8%) cases (group II). In group I, renal manifestations were present in 20 cases and absent in 34 cases. In group II, renal manifestations were present in 32 cases and were absent in 63 cases. Nephrolithiasis and nephrocalcinosis were present in 45(30.2%) and 7(4.7%) cases respectively in study population compared to 8(1.23%) persons of control group of 650 subjects. Pearson’s chi-square analysis showed that the difference in the rate of renal manifestations was significant (p < 0.001) between study population and control group. However, with in the study population the rate of renal manifestations between group I and group II was not significantly different (p = 0.137).Conclusion: This study showed eighteen fold increased renal manifestations in the patients with PHPT imaged for parathyroid gland compared to the subjects not affected by the disorder. Symptomatic variant of PHPT with renal manifestation was higher in this study compared to western countries. During parathyroid scanning in PHPT routine ultrasonographic evaluation of kidneys is necessary to exclude renal manifestation, even with negative parathyroid scan.Bangladesh J.

Background: Inguinal hernia repairs are one of most common surgeries performed world-wide. Inguinal hernias are present in 1.7% of the world population.Methods: Total of 100 patients was included in this study with 50 patients in each group. Group I (n=50): patients in this group underwent hernia repair using open preperitoneal mesh procedure. Group II (n=50): patients in this group underwent hernia repair using Lichtenstein procedure.Results: The proportion of patients with left inguinal hernia was higher in group I (48.00%) as compared to group II (46.00%), but this difference was not statistically significant. In overall study population (81.25%) as well as in group I (82.50%) and group II (80.00%) of the study, no history of straining was observed in the majority of the cases. Though the proportion of straining was higher in group I (32.00%) as compared to group II (26.00%), but this difference was not statistically significant (p=0.775). Chronic pain (see Table 4) was found in 28.75% of total patients, though the chronic pain was found in higher proportion of patients of group II (32.0%) as compared to group I (22.0%).Conclusions:In conclusion, this study shows that the TPT provides significant advantages over the Lichtenstein technique in case of repair of unilateral inguinal hernias. Patients in TPT group had less incidence of wound induration and chronic groin pain. They were also able to return to their jobs earlier.

Background: UTIs are one of the most common infectious diseases encountered in out-patient departments on day to day basis. Nitrofurantoin and Ciprofloxacin are most commonly used antibiotics in the treatment of UTI. The present study was done to compare the efficacy and tolerability of nitrofurantoin and ciprofloxacin in patients of urinary tract infection.Methods: This prospective, open, randomized, parallel group, comparative study was conducted on 60 patients presenting with acute/uncomplicated or recurrent urinary tract infection in the outpatient Department of Urology, Rajindra Hospital attached to Govt. Medical College, Patiala, Punjab. They were divided into two groups, Group I and Group II of 30 cases each. Group I patients were put on Nitrofurantoin and Group II patients were put on Ciprofloxacin. Initially 100 patients were enrolled but only those who showed growth of uropathogens on baseline urine culture or those who completed the treatment were included in the study. The primary outcome measure was microbiological eradication on post treatment urine culture.Results: The age range of the patients in Group I and Group II was 19 to 68 years (43.40±14.58 years) and 20-60 years (39.77±13.49 years) respectively. The total no. of males and females who participated in this study were 32 (53.33%) and 28 (46.66%) respectively. The most common uropathogen associated with uncomplicated UTI was E. coli (80%), other organisms detected were Klebsiella species (16.67%), Staphylococcus aureus (3.33%) and Providencia (3.33%). Post treatment urine culture results showed significant difference between two groups, 5 patients (16.67 %) in case of Group I and 14 patients (46.67%) in case of Group II showed growth of micro-organisms post treatment. P-value comes out to be 0.017 which is significant.Conclusions: In this era of super bugs, nitrofurantoin is more efficacious than ciprofloxacin in the treatment of UTI. E. coli was found to be major organism causing UTI. Ciprofloxacin is less effective due to increasing antibiotic resistance among uropathogens. Both the drugs were well tolerated, no major significant adverse effects were encountered.

Tract Infections

Introduction: Urinary tract infections are the second most common type of bacterial infection in children. Atypical infections may be associated with a higher future risk of chronic kidney disease. The current range of diagnostic tests in children with a history of urinary tract infections is still a subject of discussions. Aim of the study: We attempted to determine the indications for renal scintigraphy and develop a nephrological care model for children aged ≤24 months based on the analysis of urinary tract infections in this group of patients. Materials and methods: We included 61 children aged ≤24 months [42 (68%) girls and 19 (32%) boys], hospitalised in the Department of Paediatrics, Paediatric Nephrology and Allergology, Military Institute of Medicine in Warsaw from 2008 to 2015 due to their first episode of urinary tract infection, in our retrospective analysis. Depending on the result of DMSA static renal scintigraphy performed 6 months after completed treatment of urinary tract infection, patients were classified into 3 groups: normal scintigraphy (group I), irregular tracer uptake indicating a suspicion of post-inflammatory renal pole lesions (group II), and signs of hypodysplasia (group III). The following variables were compared: age at first infection, gender, fever, inflammatory markers, aetiology, ultrasonographic findings, and the results of voiding cystourethrography for vesicoureteral reflux. Results: The median age at the time of first infection was 5.5 months in group I, 7 months in group II, and 7.5 months in group III. Febrile urinary infection was reported in 6/21 patients in group I, 4/19 patients in group II, and 6/21 patients in group III. Increased C-reactive protein was observed in 7/21 patients in group I, 6/19 patients in group II, and 6/21 patients in group III. Recurrent infections were reported for 5/21 children in group I, 8/19 in group II, and 12/21 children in group III. Atypical aetiology of urinary infection was reported for 3/21 patients in group I, 2/19 in group II, and 2/21 in group III. Abnormal ultrasonographic findings were observed in 4/21 patients in group I, 1/19 patients in group II, and 4/21 patients in group III. Vesicoureteral reflux in voiding cystourethrography was reported in 5/21 patients in group I, 8/19 patients in group II, and 10/21 patients in group III. The analysis of all the investigated parameters showed no statistically significant differences between the groups. Conclusions: Renal scintigraphy should be performed in the youngest children with a history of urinary tract infection as it was not possible to identify patients with post-inflammatory renal scarring secondary to urinary tract infection based on the course of infection, its aetiology, ultrasound findings and the presence of vesicoureteral reflux. Ultrasonography was not sensitive enough to diagnose renal hypodysplasia in our group of children.

Background: Endometriosis is a common gynaecological disorder which is found in about5% of women and in 30% of infertile women. Identification of risk factors and timely interventionis useful. Methods: A case control study was conducted in the Dept. of obs & gynae of BangabandhuSheikh Mujib Medical University, Shahbag, Dhaka, from October 2015 to March 2016 on50 infertile patients attending the Infertility unit of the institute with the objective to determinethe risk factors of endometriosis. Twenty five women with endometriosis was taken ascases (group-I) and twenty five women without endometriosis was taken as controls(group-II). Result: The mean age was 32.8±5.4 years in group I and 35.1±5.7 years in group II which issimilar. Urban residents were 3.21 times (with 95% CI 0.87-12.71%) more likely to developendometriosis than rural resident which was statistically significant (p<0.05).Among the study population BMI of 72% patients in group I and 68% in group II were within19-24 kg/m2. The difference was not statistically significant (p>0.05) . There was notstatistically significant difference (p>0.05) between two groups in OCP use (84%vs80%).Women with endometriosis had less physical activity than the women without endometriosis;the differences was statistically significant (p<0.05). Consumption of caffeine, red meat,vegetables and fruits has no effect on endometriosis. Women with pain during menstruationwere 29.33 times (with 95% CI 5.17-100%) and women with heavy amount of blood flow were5.09 times (with 95% CI 1.24-22.06%) more likely to be endometriosis, which was statisticallysignificant (p<0.05) . Other risk factors like- age, occupation, educational status, age atmenarche and cycle length were not significantly (p>0.05) associated with endometriosis. Conclusion: Urban residence and all types of physical activities d”1 hour per day weresignificantly higher in infertile women with endometriosis.

Abstract Background Double J ureteral stents are widely used on urological patients to provide drainage of the upper urinary tract. Unfourtunately, ureteral stents are not free from complications, as bacterial colonization and require a second procedure for removal. The purpose of the current comparative experimental study is to evaluate a new heparin-coated biodegradable antireflux ureteral stent (BraidStent®-H) to prevent urinary bacterial colonization. Methods A total of 24 female pigs were underwent determination of bacteriuria and nephrosonographic, endoscopic and contrast fluoroscopy assessment of the urinary tract. Afterward, were randomly assigned animals to Group-I, in which a 5Fr double-pigtail ureteral stent was placed for 6 weeks, or Group-II, in which a BraidStent®-H was placed. Follow-up assessments were performed at 1, 3, 6, 8, 12 weeks. The final follow-up includes the above methods and an exhaustive pathological study of the urinary tract was accomplished after 20 weeks. Results Bacteriuria findings in the first 48 h were significant between groups at 6 h and 12 h. Asymptomatic bacteriuria does not reach 100% of the animals in Group-II until 48 h versus Group-I where it appears at 6 h. The weekly bacteriuria mean rate was 27.7% and 44.4% in Group I and II respectively, without statistical significance. In Group II there were no animals with vesicoureteral reflux, with statistical significance at 3 and 6 weeks with Group-I. The 91.2% of stents in Group-II were degraded between 3 and 6 weeks, without obstructive fragments. Distal ureteral peristalsis was maintained in 66.6–75% in Group-II at 1–6 weeks. Conclusions The heparin coating of BraidStent® allows an early decrease of bacterial colonization, but its effectiveness is low at the long term. Heparin coating did not affect scheduled degradation rate or size of stents fragments. BraidStent®-H avoids the side effects associated with current ureteral stents, thus should cause less discomfort to patients.
