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.

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.

Thermophysical Properties of Alkanone + Aromatic Amine Mixtures at Varying Temperatures.

In the present investigation, an attempt has been made to evaluate internal pressure ( P i ) , energy ( Δ E v a p ) , and enthalpy of vaporization ( Δ H v a p ) along with excess entropy ( S E )   and excess isothermal compressibility ( ß T E ) for binary solutions of alkanones (2-propanone, 2-butanone, and 2-heptanone) and aromatic amines (aniline, N-methylaniline, and pyridine) at 293.15, 298.15, and 303.15 K, respectively. The cohesive energy density (CED) and solubility parameter ( δ ) are studied to understand the strength of molecular interactions. The coefficient of thermal expansion ( α ) and isothermal compressibility ( ß T ) have also been investigated using empirical equations and have been employed to understand the molecular interactions. All the evaluated properties have been used to understand the nature and extent of intermolecular interactions taking place. The observed trends in the properties and their variations have been discussed in terms of varying chain lengths of the alkyl group and the hydrogen bonding capability of the components. The findings show that the extent of interactions follows an order: aniline > NMA > pyridine, keeping the alkanone constant at all the temperatures under study.

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.

RENAL nephrometry score: Predicting perioperative outcomes following open partial nephrectomy.

BACKGROUND: Partial nephrectomy has emerged as a standard treatment for small renal masses offering oncologic control equivalent to radical nephrectomy, with preservation of renal function and evidence for equivalent survival. In this study, we evaluated RENAL nephrometry score (RNS) in predicting perioperative outcomes in patients with partial nephrectomy. MATERIALS AND METHODS: This was a prospective observational study conducted from February 2016 to August 2017 which included patients who underwent partial nephrectomy. The patients were divided into three groups depending on the complexity scores (low, moderate, and high). Tumors were assigned RNS and tumor-node-metastasis staging of the clinically malignant tumors was done. Blood loss, warm ischemia time (WIT), and surgical complications were assessed. RESULTS: A total of 20 patients underwent open partial nephrectomy during the study. There were 4 (20%) low, 11 (55%) moderate, and 5 (25%) high-complexity lesions. Blood loss was significantly different in three groups. All the cases in high-complexity group were performed with clamping the renal vessels with a mean WIT of 29 min. The overall complication rates were significantly different between the groups (P = 0.007); however, majority of the complications were low grade (Grades I and II) and were managed conservatively. CONCLUSION: In the present study, RNS was correlated with predicting surgical access route, need for clamping during partial nephrectomy, blood loss, decrease in glomerular filtration rate of operated kidneys, postoperative complications, and tumor grade.

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.

Association and prognostic value of serum Cystatin C, IL-18 and Uric acid in urological patients with acute kidney injury.

PURPOSE: To assess the role of serum Cystatin C, IL-18 and Uric acid in acute kidney injury (AKI) in urological patients, along with their prognostic significance. MATERIALS AND METHODS: Prospective observational study included 61 cases, admitted in urology ward with baseline serum creatinine ≤1.5 mg/dL. All patients had at least one or more predisposing factors for AKI. Daily urine output and creatinine level were checked. Serum levels of biomarkers were measured at baseline and postoperatively after 24 h. Development of AKI and its outcome were analysed. RESULTS: Thirty nine patients (63.9%) developed AKI in the study. Patients with AKI were found to have a greater percentage rise of Cystatin C (118.7% v/s 81.8%, p = 0.005), IL-18 (59.0% v/s 25.5%, p = 0.004) and Uric acid (34.3% v/s 19.2%, p = 0.008) after 24 h. Absolute Uric acid level at day 1 was also significantly associated with AKI (5.18 ±â€¯0.91 v/s 4.45 ±â€¯0.86, p = 0.003). Risk stratification of AKI was poor for all biomarkers. Area under curve for Cystatin C, IL-18 and Uric acid was 0.715, 0.696 and 0.734 respectively. Renal function after 3 months, had a positive correlation with baseline creatinine and baseline Cystatin C levels (r = 0.56 & 0.39). CONCLUSIONS: Postoperative serum Cystatin C, IL-18 and Uric acid after 24 h were significantly associated with AKI. Baseline Cystatin C had moderate capability to predict short term renal function.

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.

Predictive factors for residual tumor and tumor upstaging on relook transurethral resection of bladder tumor in non-muscle invasive bladder cancer.

CONTEXT: Relook transurethral resection of bladder tumor (TURBT) improves the diagnostic and therapeutic efficacy of primary TURBT. However, it is still not established as to which category of patients would benefit most from this repeat invasive procedure. AIMS: This prospective interventional study was designed to identify the category of patients with non-muscle invasive bladder cancer who may benefit from a routine relook procedure. SETTING AND DESIGN: A total of 52 consecutive patients with biopsy proven non muscle invasive bladder cancer on primary TURBT underwent a relook TURBT between March 2011 and September 2012. MATERIALS AND METHODS: The incidence of residual tumor and tumor upstaging on relook procedure was correlated with various histopathological (stage, grade, CIS, presence of muscle) and cystoscopic (type and focality of tumor, any apparent field change) parameters on primary TURBT. RESULTS: Out of the total 52 patients, 23 (44.2%) had a residual tumor on relook TURBT. 12 (23.1%) were upstaged (of these 9 i.e. 17.3% to muscle invasion). While most of the parameters studied showed a positive correlation with incidence of residual tumor and upstaging to muscle invasion, statistical significance (for both) was reached only for tumor stage (P = 0.028 and 0.010), tumor grade (P = 0.010 and 0.002) and tumor type (solid vs. papillary; P = 0.007 and 0.001). Carcinoma in situ showed a significant correlation with incidence of residual tumor (P = 0.016) while the absence of muscle in the primary TURBT specimen was significantly associated with upstaging to muscle invasive disease (P = 0.018). STATISTICAL ANALYSIS: The data was analyzed using SPSS software v. 16.0. CONCLUSIONS: Relook TURBT may be especially recommended for high grade and T1 tumors and tumors with a solid/sessile appearance on primary TURBT especially when deep muscle was absent in the primary TURBT specimen.

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.

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.

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.

Study of mutated p53 protein by immunohistochemistry in urothelial neoplasm of urinary bladder.

It is difficult to predict which urothelial neoplasm would subsequently recur or progress to muscle invasive tumours or produce metastasis.The aim and objective of the study were to evaluate the scope of immunohistochemical expression of p53 in human urothelial neoplasms with regard to grade, stage and outcome of the patients. Eighteen consecutive patients were taken and urothelial tumour samples were obtained from transurethral resection or surgical excision. Histopathological examinations were performed and the grading was done according to the WHO/ISUP consensus classification of urothelial neoplasms. Immunohistochemical staining for p53 was performed on formalin fixed paraffin embedded tissue sections with appropriate positive and negative control. It was found 3 patients with papillary urothelial neoplasm of low malignant potential (PUNLMP), 5 cases of papillary low grade urothelial carcinoma, 10 patients with papillary high grade urothelial carcinoma including 2 cases of invasive urothelial carcinoma. All three PUNLMP cases showed negative results. Four out of 5 low grade papillary urothelial carcinoma had nuclear p53 accumulation, while all of the 10 papillary high grade carcinoma had high p53 index. The finding of negative p53 staining in PUNLMPs and high p53 index in high grade papillary urothelial carcinomas and invasive carcinomas support the notion that mutation of p53 gene might be unrelated to the development of urothelial neoplasms but definitely play a crucial role in progression of the malignancy.

Labetalol for prophylactic treatment of intractable migraine during pregnancy.

Headaches tend to improve in the majority of migraineurs during pregnancy, but some patients report a worsening of migraine and present a management challenge because of the restrictions of pharmacotherapy during pregnancy. Treatment options become even more limited for pregnant migraineurs who develop preeclampsia. Labetalol was tried successfully in reducing the frequency, duration, and intensity of migraine attacks in a pregnant woman with preeclampsia. There were no significant side effects and the patient delivered a healthy baby without complications.
