Modified Technique of Doubly Folded Peritoneal Flap Interposition in Transabdominal Vesicovaginal Fistula Repair: Our Experience of 36 Cases.

PURPOSE: Correction of vesicovaginal fistula (VVF) using interpositional flaps is an established procedure. In open repair, omental flap gives good results. However, its availability in all the cases is questionable. We utilized our technique of doubly folded peritoneal flap and assessed the outcome of the repair. METHODS: Retrospective observational study included 36 cases of open VVF repair, performed during 2010-2019. Preoperative clinical examination, cystoscopy, and imaging were performed routinely. Open transvesical repair as described by O'Conor was performed and doubly folded peritoneal flap was utilized. Intra- and postoperative parameters were recorded. The outcome was assessed after 21 days of catheter removal. A minimum of 6 months of follow-up was done. RESULTS: Mean age was 44 ± 18 years, and 97.2% of VVF were iatrogenic, mainly after hysterectomy (75.0%) and caesarean section (22.2%). Fistula size ranged from 0.6 to 5.5 cm. Five cases had multiple fistulas and 3 cases were recurrent. Mean flap length and width were 8.0 ± 2.4 and 5.1 ± 1.1 cm, respectively. Mean operative time and estimated blood loss were 94 ± 15 min and 155 ± 45 mL, respectively. Fourteen of 36 patients developed complications of Clavien-Dindo grade I/II. Thirty-five out of 36 cases (97.2%) were cured and remained dry for 6 months after surgery. Three cases reported de-novo urgency and were treated medically. Satisfaction level was good in 91.2% of cases. CONCLUSION: Transvesical repair using doubly folded peritoneal flap provides an excellent and durable outcome. It is a suitable alternative to the omental interpositional flap.

A novel triple oral regime provides effective analgesia during extracorporeal shockwave lithotripsy for renal stones.

CONTEXT: Analgesia during extracorporeal shockwave lithotripsy for renal stone is an essential component. It not only makes the procedure comfortable but also increases the stone-free rate. AIMS: The aim of this study was to evaluate the efficacy of triple oral analgesic agents on stone fragmentation and pain relief in comparison to injectable analgesic agents. SETTINGS AND DESIGN: This prospective randomized study included 68 patients of renal calculi of size 5-15 mm. SUBJECTS AND METHODS: Group A had 32 patients, who received injection pentazocine and injection diclofenac, 45 min before the procedure. Group B consisted of 28 patients, who received a combination of oral acetaminophen, 325 mg, oral diclofenac 50 mg, and oral tramadol 37.5 mg, 45 min prior. Procedural findings, pain score visual analog scale (VAS), fragmentation rate, and outcome were recorded. STATISTICAL ANALYSIS USED: Independent t-test and Pearson's correlation test. RESULTS: A total of 60 patients were analyzed. The mean age was 40.2 ± 11.8 years. Both groups were comparable in body mass index, stone size, number, and density. Group A required more shocks than Group B (4274 vs. 3693, P = 0.043). A lower energy level of shocks (kV) was tolerated in Group A (2.5 vs. 3.2, P = 0.002). Group A required more sittings than Group B (2.3 vs. 1.9, P = 0.037). VAS score was significantly less in Group B (2.9 vs. 4.9, P = 0.0001). The overall fragmentation rate was similar among groups (81.2% vs. 89.3%); hence, the successful outcome was (59.4% vs. 75.0%, P = 0.274). The occurrence of adverse events was also equivalent in both groups (P = 0.199). CONCLUSIONS: Triple oral regime provides better analgesic effect and quicker stone-free rate than injectable agents but with similar final outcome.

Isolated Involvement of Penis in Fournier's Gangrene: A Rare Possibility.

skin and subcutaneous tissue. Penis may be secondarily affected in some cases; however, primary isolated involvement of penis is rare. A 48-year male smoker presented with pain and blackish discoloration of the distal part of penis for the last 4 days which developed following rupture of a papulo-vesicular lesion over the prepuce of penis. It rapidly progressed to involve half of the skin of the penis. The patient was hospitalized and broad spectrum antibiotics were administered parenterally. Emergency wound debridement and urinary diversion by suprapubic cystostomy was done. After repeated wound debridement and dressings, the wound healed. Our case was unusual as the penis was the sole site of affection, which is very unusual and only few such cases are reported in the literature.

Bilateral Staghorn Calculus with Forgotten Double J Stent in Ileal Conduit Patient - A Rare Urological Challenge.

Forgotten DJ stent associated stone formation is not an uncommon entity. Here we are reporting the uncommon case of bilateral staghorn calculus due to forgotten DJ stent who had undergone radical cystectomy with ileal conduit diversion six years back. Management of these cases is a challenging urological situation due to inaccessible ureteric orifices. Patient was successfully treated with minimally invasive therapy in the form of combined bilateral PCNL (Percutaneous Nephrolithotomy) and ESWL (Extracorporeal Shock Wave Lithotripsy) therapy. The purpose of reporting this case is to highlight the grave consequences of a forgotten DJ stent and to discuss the difficulties encountered during the surgical steps of stone removal.

Can a brief period of double J stenting improve the outcome of extracorporeal shock wave lithotripsy for renal calculi sized 1 to 2 cm?

PURPOSE: Extracorporeal shock wave lithotripsy (ESWL) is an established modality for renal calculi. Its role for large stones is being questioned. A novel model of temporary double J (DJ) stenting followed by ESWL was devised and outcomes were assessed. MATERIALS AND METHODS: The study included 95 patients with renal calculi sized 1 to 2 cm. Patients were randomized into 3 groups. Group 1 received ESWL only, whereas group 2 underwent stenting followed by ESWL. In group 3, a distinct model was applied in which the stent was kept for 1 week and then removed, followed by ESWL. Procedural details, analgesic requirements, and outcome were analyzed. RESULTS: Eighty-eight patients (male, 47; female, 41) were available for analysis. The patients' mean age was 37.9±10.9 years. Stone profile was similar among groups. Group 3 received fewer shocks (mean, 3,155) than did group 1 (mean, 3,859; p=0.05) or group 2 (mean, 3,872; p=0.04). The fragmentation rate was similar in group 3 (96.7%) and groups 1 (81.5%, p=0.12) and 2 (87.1%, p=0.16). Overall clearance in group 3 was significantly improved (83.3%) compared with that in groups 1 (63.0%, p=0.02) and 2 (64.5%, p=0.02) and was maintained even in lower pole stones. The percentage successful outcome in groups 1, 2, and 3 was 66.7%, 64.5%, and 83.3%, respectively (p=0.21). The analgesic requirement in group 2 was higher than in the other groups (p=0.00). Group 2 patients also had more grade IIIa (2/3) and IIIB (1/2) complications. CONCLUSIONS: Stenting adversely affects stone clearance and also makes the later course uncomfortable. Our model of brief stenting followed by ESWL provided better clearance, comfort, and a modest improvement in outcome with fewer sittings and steinstrasse in selected patients with large renal calculi.

Differential regulation of urine proteins in urothelial neoplasm.

Urothelial neoplasm of the urinary bladder has a high rate of multifocality and recurrence. To understand this we first need to understand the changes in the molecular level that distinguishes a normal individual from a patient and also a low grade neoplasm from a high grade. In this work we aim to study the urine proteome of Indian patients with urothelial neoplasm categorised on the basis of their p53 immunohistochemistry. The urine samples of pre-operative patients were subjected to two dimensional gel electrophoresis followed by densitometric analysis and spot identification using MALDI mass spectrometry. Our study shows that few proteins such as albumin, alpha 1 antitrypsin, apolipoprotein A1, transferrin, transthyretin, haptoglobin and haemoglobin ß chain were upregulated and inter alpha trypsin inhibitor heavy chain was downregulated in the disease samples. Further we have reported that some of these proteins show an association with disease severity. The present study marks the first step in the identification of new diagnostic markers as well as therapeutic targets. BIOLOGICAL SIGNIFICANCE: Bladder carcinoma is the ninth most common cancer worldwide. It has gained attention within both clinicians and cancer biologists because of its recurrence and mortality rate. Identifying the prognostic factors of progression is a challenge, so that high risk patients who may be a candidate for a radical cystectomy may be identified. In this study we have attempted to study the changes observed in the urinary protein levels of urothelial neoplasm patients. The samples were graded based on p53 immunohistochemistry staining. We have reported eight (8) proteins, mostly highly abundant; those have exhibited differential regulation in case of diseased samples. This study is first of its kind that associates the changes in the urinary protein levels to that of the severity of the disease. We believe that the findings can be used as a stepping stone in the development of a noninvasive prognostic tool for the disease. This article is part of a Special Issue entitled: Proteomics in India.

Pure primary small cell carcinoma of urinary bladder: A rare diagnostic entity.

Small cell carcinoma of the bladder is a rare, aggressive, poorly differentiated neuroendocrine neoplasm accounting for only 0.3-0.7% of all bladder tumors. Since the tumor is very rare, pathogenesis is uncertain. Small cell carcinomas of the urinary bladder are mixed with classic urothelial carcinomas or adenocarcinomas of the bladder in 68% cases, making pure primary small cell carcinoma even a rarer entity. The unknown etiology and natural history of small cell carcinoma of the urinary bladder represent a challenge both to the pathologist and urologists for its diagnosis and treatment, respectively.

Multilocular cystic renal cell carcinoma a diagnostic dilemma: A case report in a 30-year-old woman.

Multilocular cystic renal cell carcinoma (MCRCC), also known as multilocular clear cell renal cell carcinoma (RCC), is a rare cystic tumor of the kidney with an excellent outcome. It occurs in about 3.1-6% of the conventional RCC. It is usually included in the group of tumors of undetermined malignant potential with low nuclear grade. We present a case of MCRCC in a 30-year-old female patient presenting incidentally as an apparently benign-looking multicystic space occupying lesion in the upper pole of right kidney. Right-sided simple nephrectomy was performed, and on histopathologic examination it was found to be MCRCC, stage 1 with Fuhrman nuclear grade 1. Immunohistochemistry with epithelial membrane antigen and vimentin confirmed the diagnosis.

Penile tuberculosis following intravesical Bacille Calmette-Guérin immunotherapy.

Bacille Calmette-Guérin (BCG) is an effective treatment for patients with superficial bladder cancer and bladder carcinoma in situ (CIS). It may cause side effects usually due to local and systemic inflammatory effects. We report a case of a male patient with non-invasive urothelial carcinoma of urinary bladder (Stage T1) who developed caseating granulomas on his glans penis as a complication of intravesical BCG immunotherapy. Though there are other reported cases of BCG dissemination noted in the literature, penile granuloma is rare. The first reported case was published in 1992 and since then only eleven cases are reported. It appears that both direct infectious processes and hypersensitivity reactions contribute to the clinical manifestations of a systemic BCG infection. Our case possibly represents a local infection of M bovis involving the glans penis.

Right-sided scrotal ascariasis.

We report a case of 35-year-old male patient who presented with painful right side of scrotum and worm pouting out of the scrotum. The patient had undergone surgery for strangulated right inguinal hernia 2 years back. On exploration we found multiple adult Ascaris worms in the scrotum with right-sided hydrocele. All the worms were removed and eversion of sac was done.
