Introduction. Percutaneous nephrolithotomy (PNL) is the method of choice for the treatment of patients with kidney stones larger than 2 cm. Mini-percutaneous nephrolithotomy (mini-PNL) became widespread due to reduction of injury associated with surgical approach. Creation of puncture access to the pelvicalyceal system without ureteral catheterization is also recently described. The main benefits of such technique are reduction of total operative time and the radiation exposure to the patient and medical personnel. The results of using mini-PNL without prior ureteral catheterization remain insufficiently studied, which predetermined the goal of our study. Purpose. Compare the efficacy and duration of mini-PCNL with and without ureteral catheterization. Materials and methods. We analyzed the treatment outcomes of 111 patients with a single kidney stone. Group I included 60 patients who underwent mini-PCNL according to the standard technique. Group II included 51 patients who underwent mini-PCNL without prior catheterization of the ureter. The average stone size was 19.2 0.92 mm and 18.6  0.93 mm in groups I and II, respectively. The puncture of the pyelocaliceal system of the kidney was performed under X-ray control and US guidance using the free-hand technique. Results. In group I, complete elimination of the stone was achieved in 55 (92%) patients and the mean duration of the operation was 108,3 34,85 min (range: 60 to 210). In group II, complete elimination of the stone was achieved in 50 (90%) patients and the mean duration of the operation was 69,7 22 min (range: 25 to 120 min). In all cases, the severity of complications did not exceed grade II according to Clavien classification, and their rate was 6,7% and 5,9% in group I and group II, respectively. Conclusions. According to the results of the study, the compared groups did not differ in their post-operative complication and stone-free rates. Avoidance of routine ureteral catheterization significantly reduces the operation time and hence the anesthetic risk and radiation load.

Abstract Background Percutaneous nephrolithotomy (PCNL) is a safe and efficient treatment for intro-renal diseases, most of which are calculus disease. In this study, we carried out percutaneous endoscopic nephron-sparing ablation for renal carcinoma in carefully selected patients. Our aim was to evaluate whether percutaneous endoscopic nephron-sparing operation was feasible for patients with renal cell carcinoma.Methods A total of 15 patients with renal pelvis carcinoma were treated with laser evaporation under percutaneous endoscopy between January 2015 and September 2019 ( group I ). Another 13 patients who received standard radical nephroureterectomy were recruited as the control group (group II). We recorded demographic data of the patients, the indication for surgery, tumor pathological grade, size and side of tumor, and the intraoperative and postoperative outcome, including the duration of surgery, length of hospital stay, and complication rate, as well as progression-free survival (PFS).Results In both groups, all of the patients received flexible ureteroscopy. In group I, 14 patients had transitional renal cell carcinoma (UCC), four had pathological grade I, nine had grade II, and one had hemangiopericytoma. In group II, all patients had UCC, five had pathological grade I, and eight had grade II. In group I, the mean operation time was 118 min (65–236 min), the mean blood loss was 110 ml (55–220 ml), and the mean hospital stay was 9 days (7–12 days). During follow-up, two patients died and two had recurrence; among them, one had systematic bone metastasis. The PFS rate was 66.7% (10/15). In group II, the mean operation time was 265 min (185–436 min), the mean blood loss was 133 ml (85–240 ml), and the mean hospital stay was 13 days (9–16 days). During the follow-up, two patients died and there was no local or systematic metastasis. The PFS rate was 84.6% (11/13). There was no significant difference in blood loss between the groups. However, the operation time and mean hospital stay were significantly shorter in group I compared with that in group II ( P < 0.05). But the PFS rate was significantly higher in group II than in group I (P < 0.05).Conclusions This study shows that laser evaporation under percutaneous endoscopy for renal pelvis carcinoma is a safe, effective, and technically feasible procedure for treating benign and malignant renal pelvis carcinoma.

Percutaneous nephrolithotomy (PCNL) in patients operated previously for renal stone are thought to pose some difficulties. This study was carried out to compare the outcome of PCNL in patients who had undergone open surgery for renal stone with the outcome in primary patients. This descriptive cross sectional study was conducted in the Department of Urology, Bangabandhu Sheikh Mujib Medical University, Dhaka during the period of Nov 2012 to Oct 2013. Sixty patients with renal stone admitted in urology department were selected of which 30 cases were with recurrent stone having previous open renal stone surgery (group I - study group) and another 30 were primary patients without previous surgery for renal stone disease (group II - control). After PCNL all the patients were followed at one week, one month and three months after procedure. Mean ages of Group I and Group II were 40.90 ± 6.08 years and 44.10 ± 9.91 years respectively. Mean stone size of the respondents in Group I was 2.98 ± 0.65 cm and in Group II was 3.03 ± 0.67 cm. Mean operation time of the respondents in Group I and Group II were 1.50 ± 0.46 and 1.52 ± 0.33 hours respectively. Mean post-operative hospital stay of the respondents in Group I was 3.87 ± 1.13 days and Group II was 3.67 ± 0.60 days. Stone was cleared from 29 (96.7%) patients in Group I and 28 (93.3%) patients in Group II. Mean drop of Haemoglobin level were 0.85 ± 0.55 mg/dl and 0.94 ± 0.52 gm/dl in group I and group II respectively. It was evident from the study that previous open stone surgery does not alter the outcome of subsequent PCNL.Bangladesh Med J. 2016 Jan; 45 (1): 36-39

Introduction: Percutaneous Nephrolithotripsy (PCNL) is one of the most accepted surgical modality for removal of renal stone. Placement of a nephrostomy tube at the end of PCNL is a standard procedure for PCNL, however many reports have showed the safety and efficacy of tubeless PCNL for the removal of renal stone. Aims: The present study aimed to report the outcomes of PCNL with or without nephrostomy tube. Methods: It is Prospective Hospital Study conducted from June 2017 to April 2020 in the Department of Urology Nepalgunj Medical College. Total 153 patients under inclusion criteria were divided into two groups. Group 1 (75 patients) was allocated to patients who were   being treated under standard PCNL procedure while Group 2 (78 patients) was allocated for patients who were being treated under Tubeless PCNL procedure. The two groups were compared for operation time (minutes), hospital stay (days), post operative dose of analgesic (mg), post operative complications such as, leakage (%), bleeding (%) and infection (%). Data were analyzed from SPSS and p-value less than 0.5 was considered as significant. Results: In Group II the mean hospital stay, analgesic dose and rate of leakage was significantly lesser than Group I (p<0.05) whereas, the mean operation time, rate of infection and bleeding were not significantly different between two groups (p>0.05). Conclusion:  Tubeless PCNL procedure causes more rapid recovery and earlier discharge from the hospital, reduction in postoperative pain and no leakage when compared to standard tubless PCNL.

Objective: Bleeding is one of the most common and alarming complication of percutaneous nephrolithotomy (PCNL). In this study, we aimed to compare the effects of ciprofloxacin and cefuroxime on the bleeding in PCNL procedures. Methods: The study was a retrospective analysis of 97 patients who underwent PCNL between February 2011 and June 2017. We just included the patients who had single tract lower pole PCNL for more objective evaluation of bleeding in the study. The patients were divided into two groups as ciprofloxacin group (Group-I, n:40) and cefuroxime group (Group-II, n:56) according to the type of antibiotic used in the operation. Patient age, gender, body mass index, stone size, preoperative INR, preoperative and postoperative platelet counts and difference, operative time, need for blood transfusion, postoperative fever, hospital stay, postoperative hemoglobin and hematocrit drop were analyzed. Results: There was no statistically significant difference in patients’ gender distribution, body mass index, preoperative INR, preoperative and postoperative platelet counts, preoperative and postoperative platelet difference, duration of operation, hospital stay, postoperative fever and need for postoperative blood transfusion between two antibiotic groups (p > 0.05). Mean patient age was 42,75±16,97 in Group-I and 35,54±14,71 in Group-II (p < 0.05). The mean stone size of Group-I and Group-II were 27,23±7,05 mm and 30,59±8,20, respectively (p < 0.05). The mean postoperative hemoglobin and hematocrit drop were significantly higher in Group-I than in Group-II. The mean hemoglobin drop was 1,73±0,95 for Group-I and 1,28±0,67 for Group-II (p < 0.05). The mean hematocrit drop was 5,17±2,76 for Group-I and 3,80±1,99 for Group-II (p < 0.05). Conclusion: On the basis of the results of the initial study, the antibiotic preference in patients undergoing surgery may be one of the bleeding factors during and after PCNL. doi: https://doi.org/10.12669/pjms.36.4.1977 How to cite this:Akkoc A, Aydin C, Ucar M, Topcuoglu M.

Background: CIN has gained increased attention in the clinical setting, particularly during cardiac intervention but also in many other radiological procedures in which iodinated contrast media are used. There is at present good clinical evidence from well-controlled randomized studies that CIN is a common cause of acute renal dysfunction.Methodology: This was a prospective study conducted among the patients who underwent coronary angiography and percutaneous coronary intervention in the Department of Cardiology, Dhaka Medical College Hospital during January 2010 to December 2010. A total of 111 patients age range from 25 to 75 years were included in the study. Serum creatinine level at baseline and at the end of 48 hours was done in all these patients. Study population was divided into two groups according to development of acute kidney injury (AKI). Group-I = AKI, Group II = Not developed AKI. Results: AKI developed 11.7% of the study patient. DM and Preexisting renal insufficiency were significantly higher in group I patients. HTN was (61.5% Vs 44.9%) higher in group I but not significantly. History of ACE inhibitor/ARB, NSAID intake and LVEF <40% were significantly higher in group I patients. The mean±SD volume of CM (Contrast Media) were 156.9±44.8 ml and 115.4±30.0 ml in group I and group II respectively, which was significant. The mean±SD of serum creatinine after 48-72 hours of CAG/PCI was 1.4±0.37 mg/dl and 1.1±0.2 mg/dl in group I and group II respectively. The serum creatinine level increased significantly (p<0.05) after 48-72 hours of CAG/PCI in group I. In group II, S. creatinine level increased but not significant (p>0.05). Impaired renal function was found 76.9% and 2.0% in group I and group II respectively. DM, HTN, preexisting renal insufficiency, ACE inhibitor/ARB, NSAIDs, contrast volume (>150 ml), eGFR (<60 ml/min/ 1.73m2) and LVEF (<40%) are significantly (p0.05) associated for CIN development.Conclusion: CIN is an iatrogenic but preventable disorder results from the administration of contract media. Although rare in the general population, CIN occurs frequently in patients with underlying renal dysfunction and diabetes. In patients with pre angiographic normal renal function, the prevalence is low but in pre-existing renal impairment it may pose a serious threat. Thus risk factors are synergistic in their ability to predispose to the development of CIN. A careful risk-benefit analysis must always be performed prior to the administration of contrast media to patients at risk for CIN.

Background: Labor is a naturally occurring physiological process associated with uterine contractions, effacement, dilatation of cervix and descent of presenting part. Drotaverine hydrochloride is a non-anticholinergic isoquinoline derivative which acts by elevating intracellular cyclic Adenosine Mono Phosphate (cAMP) and cyclic Guanosine Mono Phosphate (cGMP) promoting smooth muscle relaxation. Materials and Method: This was a hospital based prospective study on effectiveness of Drotaverine Hydrochloride on enhancing dilatation of cervix and acceleration of active phase of labor. The sample size was 100. Fifty cases of women in active phase of labor received injection drotaverine hydrochloride 40 mg (group i) and fifty cases of women did not receive any drug (group ii) among those at term with singleton pregnancy and vertex presentation. Variables like maternal age, interval between administration of drug and delivery, mode of delivery, apgar score at 5 minutes, NCU (Neonatal Care Unit) admission and neonatal outcomes were recorded. Data analysis was done with the help of SPSS program. Results: The mean interval between drug administration to delivery in primipara and multipara in group i was 3.05 hours and 2.31 hours while in group ii was 4.5 hours and 3.75 hours respectively. The mean interval between drug administration and delivery was shorter in both groups of multipara. In group i, 96% had normal delivery and 4 % had vacuum delivery and in group ii 90% and 10% had normal delivery and vacuum delivery respectively. None of the participants had caeserian section. There were no perinatal mortalities. Conclusion: The administration of drug Drotaverine Hydrochloride is effective in shortening duration of labor with favorable feto-maternal outcome.

Object The purpose of the present study was to evaluate the efficacy of anterior polymethylmethacrylate (PMMA) cement augmentation in instrumented anterior lumbar interbody fusion (ALIF) for patients with osteoporosis. Methods Sixty-two patients with osteoporosis who had undergone single-level instrumented ALIF for spondylolisthesis and were followed for more than 2 years were included in the study. The patients were divided into 2 groups: instrumented ALIF alone (Group I) and instrumented ALIF with anterior PMMA augmentation (Group II). Sixty-one patients were interviewed to evaluate the clinical results, and plain radiographs and 3D CT scans were obtained at the last follow-up in 46 patients. Results The mean degree of cage subsidence was significantly higher in Group I (19.6%) than in Group II (5.2%) (p = 0.001). The mean decrease of vertebral body height at the index level was also significantly higher in Group I (10.7%) than in Group II (3.9%) (p = 0.001). No significant intergroup differences were observed in the incidence of radiographic adjacent-segment degeneration (ASD) or in terms of pain and functional improvement. The incidences of clinical ASD (23% in Group I and 10% in Group II) were not significantly different. There was 1 case of nonunion and 3 cases of screw migration in Group I, but none resulted in implant failure. Conclusions Anterior PMMA augmentation during instrumented ALIF in patients with osteoporosis was useful to prevent cage subsidence and vertebral body collapse. In addition, PMMA augmentation did not increase the nonunion rate and incidence of ASD.

In this study, genotoxic effects of repeated sevoflurane anaesthesia were investigated in rabbits with or without antioxidant supplementation. Twenty-one New Zealand male rabbits were included in the study and randomized into three groups as: placebo treated (Group I), vitamin E supplemented (Group II) and selenium supplemented (Group III). Vitamin E and selenium were given intraperitoneally for 15 days before anaesthesia treatment. Anaesthesia was administered using 3% sevoflurane in 4 L/min oxygen for a 3-hour period and continued for 3 days. Blood samples were collected before anaesthesia (Sample 1), after the first, second and third days of sevoflurane administration (Sample 2, Sample 3 and Sample 4 respectively) and the last samples were taken 5 days after the last sevoflurane administration (Sample 5). Genotoxic damage was examined using the comet assay. The degree of damage is assessed by grading the cells into three categories of no migration (NM), low migration (LM) and high migration (HM) depending on the fraction of DNA pulled out into the tail under the influence of the electric field. The number of comets in each sample was calculated (1 × number of comets in category NM + 2 × number of comets in category LM + 3 ×number of comets in category HM) and expressed as the total comet score (TCS), which summarizes the damage frequencies. In Group I, a significant increase in the mean TCSs was observed for Samples 3 and 4 as compared with Sample 1. However, there were no significant differences between Samples 1, 2 and 5. The mean TCS of Sample 4 was significantly higher than Sample 1, 2 and 3 in Group II. Group III demonstrated no significant mean TCSs for any experimental conditions. Statistical differences were also observed between the groups with significant P values. This experimental study points out the presence of DNA damage with repeated sevoflurane anaesthesia and the genoprotective role of antioxidant supplementation on DNA damage in mononuclear leukocytes of rabbits by highly sensitive comet assay.

Objective: the clinical value of spinal quantitative CT (sQCT) and the structural patterns of the vertebral bone were studied Material and Methods: sQCT was performed on 246 patients with a mean age of 57 years for whom conventional lateral radiographies of the thoracic and lumbar spine were available. All patients were suffering from back pain of unknown etiology. the bone mineral density (BMD) of the midvertebral section of 3 lumbar vertebral bodies was determined by means of single-energy-(SE)-weighted QCT (85 kV). Spongiosa architecture and density profile analyses were made in the axial images. This was contrasted to BMD values ascertained in SE QCT. the mean BMD was compared to the number of fractures and the patients were divided into three groups: group I — no fracture; group II — one fracture; and group III 1 fracture Results: the mean BMD was: 134.3 (74.1–187.5) mg hydroxyapatite (HA)/ml in group I; 79.6 (58.6–114.3) mg HA/ml in group II; and 52.4 (13.1–79.1)mg HA/ml in group III. A significant deterioration in spongiosa structure was found with increasing demineralization: strongly rarefied patterns predominated in the fracture groups II and III Conclusion: sQCT provides a good risk assessment of the occurrence of vertebral body insufficiency fractures

The monthly wool growth of three groups of rams was studied at Beltsville, Maryland. Group I received natural daylight (at 38° 53' N.) and was shorn monthly. Group II had a 7:17 hours of daylight to hours of darkness rhythm and was shorn every 6 months, once in winter and once in summer. Group III received natural daylight and was likewise shorn every 6 months. The rams of all groups produced more wool in summer than in winter. This difference was significant (P<0.001). The mean body weight and food intake were both greater in the winter months, which indicated that the seasonal rhythm of wool growth was not a consequence of poorer feeding in winter. The rams which were shorn monthly (group I) grew considerably more wool than the other two groups, but the difference was not statistically significant. The short-day treatment of group II did not increase the annual wool production nor decrease the seasonal rhythm of wool growth. The balance of evidence from this and other experiments indicates that temperature rather than light controls the seasonal rhythm of wool growth.
