Vesicocutaneous fistula after sliding hernia repair

Sliding inguinal hernias are usually direct inguinal hernias containing various abdominal viscera. The incidence of bladder forming a part of an inguinal hernia, called as “scrotal cystocele,” is 1–4%. The risk of bladder injury is as high as 12% when repairing this type of hernia. This case report emphasizes this aspect in a 65-year-old man who presented with urinary leak through the scrotal wound following right inguinal hernia repair

Is frozen section analysis of the urethra at the time of radical cystectomy and orthotopic neobladder urinary diversion mandatory?

Introduction: This study was aimed at analyzing the need for routine use of frozen section analysis (FSA) before performing orthotopic neobladder (ONB) after radical cystectomy for carcinoma urinary bladder. Materials and Methods: A total of 233 patients underwent radical cystectomy from January 2000 to June 2013. Of these, 151 (65.6%) patients were planned for ONB. In the initial 109 (72%) patients, FSA of urethral margin was performed, but, in the subsequent 42 (28%) patients, frozen section of urethral margin was not sent. Impact of hydroureteronephrosis, tumor size and location of tumor in relation to the bladder neck on the status of the urethral margin was analyzed. Results: Only three of the 109 (2.7%) patients had a positive urethral margin. Two of them had ileal conduit and one, after negative re-resection, had ONB. Although none of the factors was found to be significant, all three patients with a positive urethral margin had growth at the bladder neck and died of cancer at a mean follow up of 29.33 ± 18.3 months, without urethral recurrence. Among the negative FSA (106), two patients had recurrence in the penile urethra. The mean follow-up was 46.3 ± 25.1 months. None of the patients without FSA (42) had urethral recurrence at the mean follow-up of 36 ± 9.3 months. Of the 28 patients who had their growth located at the bladder neck, three had positive FSA, while none with growth away from the bladder neck had positive FSA. Conclusion: Routine FSA of the urethra before performing ONB can be avoided in those patients where the tumor does not reach the bladder neck

Predictors for progression of metastatic prostate cancer to castration-resistant prostate cancer in Indians

Background & objectives: There is lack of data on natural history and progression of prostate cancer (PC) which have implications in the management of the disease. We undertook this retrospective study to analyze factors predicting progression of metastatic PC to castration-resistant prostate cancer (CRPC) in Indian men. Methods: Complete records of 223 of the 489 patients with metastatic PC were obtained from computerized data based system in a tertiary care hospital in north India between January 2000 to June 2012. Patients with follow up of 65 yr), baseline PSA (7) were recorded. Extent of bone disease (EOD) was stratified according to the number of bone lesions i.e., 10. CRPC was defined as two consecutive PSA rise of > 50 per cent from nadir or an absolute value of > 5 ng/ml. Results: Mean age of patients was 61.5 ± 12.45 yr and their PSA level was 325.6 ± 631.35 ng/dl. Of the 223 patients, 193 (86%) progressed to CRPC at median time of 10.7 (4-124) months. Median follow up was 24 (6-137) months. On univariate and multivariate analyses EOD on bone scan was found to be a significant predictor ( P=0.006) for time to CRPC. Median time to CRPC was 10 months (CI 95%, 7.5-12.48) with >10 lesions or super scan versus 16 months (CI 95%, 10.3-21.6) with <10 bone lesion (P=0.01). Ninety (46.6 %) patients of CRPC died with median time to death from time of CRPC 21 (10-120) months. Interpretation & conclusions: Median time for progression of metastatic PC to CRPC ranged from 10-16 months depending on the extent of the bone involvement. In Indians, the aggressive course of advanced prostate cancer warrants further clinical trials to explore the need for additional treatment along with initial castration

An audit of early complications of radical cystectomy using Clavien-Dindo classification

Introduction: Despite the major improvements in surgical technique and perioperative care, radical cystectomy (RC) remains a major operative procedure with a significant morbidity and mortality. The present study analyzes the early complications of RC and urinary diversion using a standardized reporting system. Materials and Methods: Modified Clavien-Dindo classification was used to retrospectively assess the peri-operative course of 212 patients who had RC with urinary diversion between October 2003 and October 2014 at a single institution. The indications for surgery were muscle invasive urothelial carcinoma, high-grade nonmuscle invasive bladder cancer (BC), and Bacillus Calmette-Guerin-resistant nonmuscle invasive BCs. Data on age, sex, comorbidities, smoking history, American Society of Anaesthesiologists score, and peri-operative complications (up to 90 days) were captured. Statistical analysis was performed using SPSS 20.0 software (Chicago, USA). Results: The mean age was 56.15 ΁ 10.82. Orthotopic neobladder was created in 113 patients, ileal conduit in 88 patients, and cutaneous ureterostomy in 11 patients. A total of 292 complications were recorded in 136/212 patients. 242 complications (81.16%) occurred in the first 30 days, with the remaining 50 complications (18.83%) occurring thereafter. The rates for overall complication were 64.1%. The most common complications were hematologic (21.6%). Most of the complications were of Grade I and II (22.9% and 48.9%, respectively). Grade IIIa, IIIb, IVa, IVb, and V complications were observed in 10.2%, 8.9%, 3.4%, 2.7%, and 2.7% of the patients, respectively. Conclusions: RC and urinary diversion are associated with significant morbidity. This audit would help in setting a benchmark for further improvement in the outcome

Is en-bloc transurethral resection of bladder tumor for non-muscle invasive bladder carcinoma better than conventional technique in terms of recurrence and progression?: A prospective study

Purpose: Conventional, transurethral resection of bladder tumor (TURBT) involves piecemeal resection of the tumor and has a very high recurrence rate. We evaluated the outcome of en-bloc TURBT (ET) in comparison with conventional TURBT (CT) in non-muscle invasive bladder carcinoma in terms of recurrencew and progression. Materials and Methods: From September 2007 to June 2011, in a prospective non-randomized interventional setting, ET was compared with CT in patients with solitary tumor of 2-4 cm size in terms of recurrence and progression. Pedunculated tumors, size >4 cm, tumors with associated hydroureteronephrosis and biopsy specimen with absent detrusor muscles were excluded. Fisher′s exact test and survival analyses were used to compare the demography and the outcome. Results: A total of 21 patients of ET were compared with 24 patients of CT. Mean tumor size was 2.8 cm in ET and 3.3 cm in CT group. Location of tumor, stage and grade were comparable in both groups. Recurrence rate was 28.6% versus 62.5% (P = 0.03) and progression rate was 19% versus 33.3% (P = 0.32) in ET versus CT group respectively. Recurrence free survival was 45.1 (95% CI: 19.0-38 months) and 28.5 (95% CI: 35.4-54.7 months) in ET and CT group (P = 0.018). Progression free survival in ET and CT was 48.32 (95% CI: 35.5-53.0 months) and 44.26 (95% CI: 39.0-57.5 months), P = 0.46. Conclusion: There was a significant reduction in the recurrence rate and time to recurrence with ET. Rate of progression was also relatively less with ET, though not statistically significant

Impact of changing trends in technique and learning curve on outcome of hypospadias repair: An experience from tertiary care center

Introduction: Apart from numerous clinical factors, surgical experience and technique are important determinants of hypospadias repair outcome. This study was aimed to evaluate the learning curve of hypospadias repair and the impact of changing trends in surgical techniques on the success of primary hypospadias repair. Materials and Methods: We retrospectively analyzed of data of 324 patients who underwent primary repair of hypospadias between January 1997 and December 2013 at our center. During the initial 8 years, repairs were performed by multiple 5 different urologists. From 2005 onwards, all procedures were performed by a single urologist. The study cohorts was categorized into three groups; Group I, surgeries performed between 1997–2004 by multiple surgeons, Group II, between 2005–2006 during the initial learning curve of a single surgeon, and Group III, from 2007 onwards after completion of the learning curve of the single surgeon. The groups were compared in respect to surgical techniques, overall success and complications. Results: Overall 296 patients fulfilled the inclusion criterion, 93 (31.4%), 50 (16.9%), and 153 (51.7%) in Group I, II, and III, respectively. Overall success was achieved in 60 (64.5%), 32 (64%), and 128 (83.7%) patients among the three groups respectively (P < 0.01). Nineteen (20.4%), 20 (40%), and 96 (62.7%) patients underwent tubularized incised plate repair in Group I, II, and III, with successful outcome in 12 (63.2%), 15 (75%), and 91 (94.8%) patients, respectively (P < 0.01). The most common complication among all groups was urethrocutaneous fistula, 20 (21.5%) in Group I, 11 (22%) in Group II, and 17 (11.1%) in Group III. Conclusion: There is a learning curve for attaining surgical skills in hypospadias surgery. Surgeons dedicated for this surgery provide better results. Tubularized incised plate urethroplasty appear promising in both distal and proximal type hypospadias

Spiral laminar flow, the earliest predictor for maturation of arteriovenous fistula for hemodialysis access

Introduction: Arteriovenous fistula (AVF) is the gold standard vascular access for hemodialysis (HD). A thrill or murmur immediately after creation of AVF is considered a predictive sign of success. However, this does not ensure final maturation for successful HD. Our objective was to determine different clinical and duplex parameters within AVF to predict maturation and subsequent successful HD. Materials and Methods: A prospective observational study was conducted on 187 patients who had AVF formation from July 2012 to May 2013. Following surgery, all patients had Doppler ultrasound (DU) on Days 0 and 7. Doppler parameters noted in the outflow vein were: Thrill, broadening of spectral waveform with increased peak systolic velocity (PSV) and spiral laminar flow (SLF). Patients with at least one positive parameter at Day 0 were followed-up serially and underwent repeat Doppler imaging on Day 7. Patients with the absence of all three parameters on Day 0 were excluded from the study. Endpoint was maturation of AVF, i.e. successful HD. Statistical analysis was performed with binary logistic regression, to find out the strongest and earliest predictor for maturation of AVF using SPSS version 20. Results: SLF and broadening of spectral waveform with increased PSV were found to have a significant association with maturation (P = 0.0001). Presence of SLF on Day 0 most strongly predicted maturation. Presence of thrill or murmur could not predict the maturation. Conclusions: SLF pattern in AVF is the most important and the earliest predictor of maturation

Multiple renal veins in donor nephrectomy-preoperative assessment of feasibility for safe and selective ligation

The aim of the study is to provide an objective preoperative assessment protocol by computerized tomography angiography by measuring the vein volume (πr2h) instead of the vein diameter for accurate size and blood flow assessment in case of multiple renal veins during donor nephrectomy. To reduce rewarm ischemia time, smaller renal veins were safely ligated without compromising drainage due to their robust intrarenal anastomotic communications. The selection of vein for safe ligation is crucial to avoid congestion and high intrarenal pressures in the allograft venous system and was made by calculating the vein volume. Application of this formula in 343 donors with multiple veins (2003–2021) has led to uneventful intra- and postoperative course. This method prevails over the existing subjective assessment techniques, thereby ensuring the best possible perfusion and drainage of the allograft
