Percutaneous nephrolithotripsy is a standard method in the treatment of nephrolithiasis, in the final stage of which nephrostomy drainage is established, but there are known methods of performing this operation without nephrostomy. This article shows our experience of performing tubeless percutaneous nephrolithotomy, as well as evaluates the safety and efficacy of tubeless PNL with placement of a JJ-stent. The objective: establish opportunities to perform a tubeless mini percutaneous nephrolithotomy and evaluate the safety and effectiveness of its implementation. Materials and methods. For the period 2017–2021. performed more than 500 percutaneous nephrolitotomy. 53 mini-PNL tubeless (II group), the other group (I group) included 58 patients who underwent mini-PNL by standard method. There were no significant differences in age and sex, location and size of stones in the study groups (p>0,05). All operations were performed under regional anesthesia. Results. The average duration of the operation in group I was 57,2±17,9 minutes, in group II 54,9±15,6 minutes (p>0,05). The average drop of hemoglobin in I group was 0,39 g/l compared with 4,1 g/l in II group. The difference between the groups was not statistically significant (p>0,05). The level of pain in this study was assessed using a visual analog scale, in group I the average pain was 3,7 compared with 1,6 in patients of II group (p<0,05). Accordingly, the necessity of analgesia for I group was higher and amounted to 58,4±17,3 mg of dexketoprofen, against 27,3±15,2 mg of dexketoprofen in the second group (p<0,05). Postoperative fever ≥38,0 °С was observed in 5 (8,6%) patients who performing the operation according to the standard method, and 1 (1,9%) of the patient (p>0,05) who performed drainage-free PNL. The stone free rate in I group was achieved in 56 (96,6%), in group II in 53 (100%) (p>0,05). The postoperative hospital stay in I group was 2,92±0,24 days, and in II group – 1,22±0,11 days (p>0,05). Analyzing the results of tubeless percutaneous nephrolithotomy, we can say that its effectiveness is due to careful selection of patients and strict compliance with the rules of PNL. Conclusions. This study demonstrates the advantages of tubeless percutaneous nephrolithotomy over standard methods in the form of reducing the level of postoperative pain, according to the need for analgesics, and reduces the duration of postoperative hospital stay. However, it should be noted that drainage techniques of percutaneous nephrolithotomy should be performed in strictly selected patients.

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.

Aim. The article discusses the results of a study using a patented method of two-layer laparoscopic repair of large and giant hiatal hernias using a biocarbon implant in comparison with other surgical techniques.Materials and methods. 716 patients were divided into 3 study groups based on the area of the size of the esophageal hernia defect: group I (314 patients) – with small (less than 5 cm2) and medium (5–10 cm2) hiatal hernias, that is, up to 10 cm2, which hernioplasty was performed only by the method of posterior cruraphy; group II (323 patients) – with large hernias 10–20 cm2: subgroup 1 (92 patients) underwent posterior cruraphy, subgroup 2 (231 patients) – alloplasty. Depending on the alloplasty technique, subgroup 2, in turn, was divided: subgroup A (89 people) – hernioplasty with a polypropylene implant and subgroup B (142 people) – hernioplasty with a medical biocarbon construction. Study group III (79 patients) – patients with giant diaphragmatic hernias of more than 20 cm2 using alloplasty: subgroup A (29 people) – hernioplasty with a polypropylene implant and subgroup B (50 patients) – alloplasty with a medical biocarbon construction.Results. When comparing group I with subgroup 1 of group II, the following results were obtained. Statistically significant differences were found in the degrees and types of diaphragmatic hernias. The average age of patients and statistical differences for it were insignificant. When comparing subgroup 1 with subgroup 2 of group II, statistically insignificant differences were found in the degrees and types of hiatal hernias. The difference in the average age of patients was also statistically insignificant. The difference in the average age of patients was also statistically insignificant. When comparing subgroup A with subgroup B of group II, statistically insignificant differences were found among themselves in the degrees and types of hiatal hernias. When comparing subgroup 2 of group II with group III, the difference turned out to be statistically significant in the distribution of patients by types and degrees of diaphragmatic hernias. When comparing subgroup A with subgroup B of group III by degrees and types of hiatal hernias, statistically insignificant differences were revealed.Conclusion. Posterior cruraphia in small and medium diaphragmatic hernias had significant statistical differences in types and degrees compared to that in large hernias, as well as in the average area of the hernial defect. Posterior cruraphia with hernioplasty in large hiatal hernias did not differ statistically significantly according to any of the criteria. Plastic surgery with a polypropylene implant with alloplasty of a biocarbon implant for large hernias did not differ significantly according to any of the criteria. Hernioplasty for large hiatal hernias, when compared with giant hernias, differed significantly only in the degree and type, as well as in the area of the hernial defect. «Onlay» plastic surgery with a polypropylene implant with alloplasty of biocarbon structures for giant hernias did not differ significantly according to any of the criteria, except for gender distribution, which did not have significant fundamental significance, which made it possible to make a more correct comparison of the results of surgical interventions in these research subgroups.

Objectives: To see the effect of intra operative antegrade flexible nephroscopy during Percutaneous nephrolithotomy on stone free rate. Methods: We retrospectively reviewed electronic medical records of patients who underwent percutaneous nephrolithotomy from 2010 to 2017 for renal stones >2cm. Patients found eligible were divided in, Group-I who did not have intraoperative Flexible nephroscopy and Group-II who had flexible nephroscopy during percutaneous nephrolithotomy. All procedures were done by senior consultants. Variables like Mean age, side, stone size, skin to stone distance and Hounsfield unit were compared. Outcomes like Stone free rate, hospital stay and operative time were compared between the groups. Results: The study included 248 patients, consisting 85 (34.3%) females and 163 (65.7%) males. Mean age ± SD was 45.8±13.8 years. Both group were similar in characteristics like mean age, stone size, skin to stone distance and Hounsfield units. The overall stone free rate was 71%. It was not significantly different between the groups, 76% in Group-II vs. 67% in Group-I. However stone free rate markedly improved with flexible nephroscopy in patients with staghorn calculi. Mean operative time and hospital stay were similar between the groups. Conclusions: Intraoperative flexible nephroscopy during percutaneous nephrolithotomy significantly increases stone free rate in patients with staghorn stones. doi: https://doi.org/10.12669/pjms.37.3.3565 How to cite this:Masood Y, Iqbal N, Farooq RM, Iqbal S, Khan F.

Abstract Objectives To investigate whether the perioperatively combined application of dexamethasone and furosemide could alleviate the inflammation in patients undergoing percutaneous nephrolithotomy (PCNL). Patients and methods 147 patients undergoing PCNL between November 2018 and October 2019 were enrolled in the study. 77 patients accepted a single dose of dexamethasone and furosemide administration (EXP group, n = 77), and 70 patients did not (CON group, n = 70). Demographic and perioperative data, inflammatory markers including interleukin-6 (IL-6) and procalcitonin (PCT), and clinical outcomes were compared between the two groups. Results Compared with the CON group, the incidence rate of urosepsis of the EXP group were significantly lower (11.69% vs. 24.29%, p = 0.046). 3 patients developed severe urosepsis in the EXP group, while 5 patients developed severe urosepsis in the CON group. Compared with those in the CON group, the patients with postoperative urosepsis in the EXP group showed lower serum levels of IL-6 at postoperative hour two (p = 0.045) and at postoperative day one (p = 0.031) and lower serum levels of PCT at postoperative day one (p = 0.015). There was a better clinical outcome of a shorter postoperative hospital stay (p = 0.015) in patients with postoperative urosepsis in the EXP group than in those in the CON group. Conclusion The perioperatively combined application of dexamethasone and furosemide was beneficial for alleviating postoperative inflammatory reaction and caused a better clinical outcome of a shorter postoperative hospital stay.

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.

BackgroundAlthough several surgical techniques for treatment of sacrococcygeal pilonidal sinus (SPND) have been described, there is no consensus on the optimal surgical procedure. In this study we compared excision with primary closure and Limberg flap in the treatment of SPND.MethodsThis was a prospective randomised clinical trial in patients with SPND who were randomly allocated to one of two groups: group I (excision and primary closure) and group II (Limberg flap technique). The primary outcome of the trial was recurrence of SPND whereas postoperative complications, return to work and cosmetic results were the secondary outcomes.ResultsSixty patients were included, with a mean age of 24.1 years and mean body mass index (BMI) of 26.8 kg/m2. Group 1 had significantly shorter operation time than group II. Both groups had similar hospital stay and comparable complication rates (43.3% vs 30%; P = 0.4). Group I had significantly higher recurrence rate (20% vs 0; P < 0.02) and significantly better cosmetic satisfaction score than group II. Being hairy (P = 0.04), positive family history (P = 0.03), diabetes mellitus (P = 0.005) and history of previous surgery for SPND (P = 0.01) were the significant predictors for recurrence.ConclusionsThe Limberg flap is an effective technique for the treatment of SPND with very low recurrence rate and comparable complication rate and hospital stay to excision and primary closure. Excision and primary closure offered the advantages of quicker healing time, earlier resumption of daily activities, better cosmetic results, which may render it more suitable for patients with low risk for recurrence.

This Randomised controlled clinical trial was undertaken to determine the suitable time of catheter removal after urogenital prolapse surgery in order to reduce the catheter related UTI and its long term sequel. Method: Total 80 patients undergoing vaginal hysterectomy with pelvic floor repair were enrolled and randomised into two equal groups by lottery method. Trans-urethral catheter was removed on 2nd & 5th post operative day in group I (n=40) and in group II (n=40) respectively. Post   voidal residual urine volume before operation and after removal of catheter was measured in   all patients by ultrasound scanning. Re-catheterisation was done for three more days if residual volume > 200ml after removal of catheter. Urine samples were taken before removal of catheter and send for routine microscopic examination and culture & sensitivity test to detect UTI.Results: Removal of catheter on 2nd post-operative day lead to significant reduction of rate of UTI. The rate of UTI following removal of catheter was 7.5% versus 42.5% in group I and in group II (p<0.001). But need for recatheterisation was significantly higher in group I (15%) than in group II (2.5%). The mean duration of catheterisation was 47.63 (±0.628) and 119.35 (±0.864) hours in group I and group II respectively. Majority of the patients in group I did not  require prolongation of catheterisation. Mean duration of hospital stay after operation was 5 days in group I and 7.95 days in group II (p<0.001). Conclusion: Short period catheterisation is associated with lower rate of UTI and shorter hospital stay. Disadvantages of prolonged catheterisation outweigh the advantages. Therefore removal of the catheter on the 2nd post-operative day after genital prolapse surgery is preferable than 5 days catheterization DOI: http://dx.doi.org/10.3329/bjog.v26i2.13782 Bangladesh J Obstet Gynaecol, 2011; Vol. 26(2) : 68-71
