Comparing T2-T3 staging of penile cancer according to the American Joint Committee on cancer 8th edition with two modified staging systems in predicting survival outcome: A single-center experience.

Introduction: Penile cancer is a rare malignancy of the genitourinary tract. We aimed to validate the recent changes in the T2 and T3 stages of penile cancer in the American Joint Committee on Cancer (AJCC) 8th edition and to compare its predictive ability with two other modified staging systems for survival outcomes. Methods: This is a retrospective study of patients diagnosed with penile cancer from June 2015 to March 2020. The AJCC 8th edition and two other newly proposed systems by Li et al. and Sali et al. were used for staging the tumor. All variables were categorized and correlated with lymph node (LN) metastases and overall survival (OS). Results: Fifty-four patients were eligible for this study. The mean age was 58 years (range 46-72 years). The tumor stage (P = 0.016), clinical LN stage (P = 0.001), the involvement of the spongiosa (P = 0.015) and the cavernosa (P = 0.002), lymphovascular invasion (LVI) (P = 0.000), and PNI (P = 0.021) were found to be the significant predictors of LN metastases. When the 5 year OS was compared between the T2 and T3 stages of the AJCC 8th edition, Li staging and the Sali staging systems, it was 91% and 50.1% (P = 0.001), 97.5% and 10.3% (P = 0.000), 94.4% and 14.7% (P = 0.000), respectively. The presence of LVI (P = 0.001) was the most significant independent predictor of OS. Conclusions: The recent changes in the AJCC 8th edition pertaining to the T2-T3 stage are relevant, although the other two newly proposed staging systems were more precise in predicting the survival outcomes.

Upper tract transitional cell carcinoma clinically mimicking inflammatory renal pathology: A report of three cases.

Upper tract urothelial carcinoma (UTUC) of the renal pelvis and the ureter is incidentally detected in a small proportion of cases. However, the majority of UTUC cases present with hematuria, flank pain, and clot colic. Typical imaging features include hydronephrosis of the kidney (s) due to obstruction by the mass with a soft-tissue lesion that typically shows low-grade enhancement with or without a filling defect. Rarely, such a tumor may present with signs and symptoms mimicking an inflammatory or infective pathology of the kidney and is diagnosed only on biopsy or on nephrectomy. We present three such patients and cite another similar case we have published earlier. All three of these patients presented with signs and symptoms of an obstructed infected kidney with long-standing renal calculi and a forgotten DJ stent in one instance. Nephrectomy for the presumed infected kidney in all three cases revealed high-grade UTUC. In patients presenting with equivocal findings on cross-sectional imaging with a history of renal calculi or foreign bodies, we should have a high index of suspicion for malignancy.

Experience with management of renal cell carcinoma with inferior vena cava/right atrial tumor thrombus.

INTRODUCTION: We aimed to present our experience in managing renal cell carcinoma (RCC) with inferior vena cava (IVC) thrombus. METHODS: Records of all patients aged 18 years and older, with a diagnosis of primary renal masses with IVC thrombus, presenting to our institute from January 2012 to August 2020 were retrospectively reviewed. Patients with tumor thrombus limited only to renal vein were excluded from the analysis. Their hospital course and outcomes were recorded and evaluated for predictors of survival. RESULTS: During the study period, we treated 61 patients with a renal mass and concurrent IVC thrombus and 56 of these underwent surgery. 7 of them had level III and 6 had level IV thrombus. A total of six patients received neoadjuvant tyrosine kinase inhibitor (TKI) therapy and all of them showed a decrease in size and level of tumor thrombus and cardiopulmonary bypass was safely avoided. Fourteen patients had distant metastasis and underwent cytoreductive surgery and of these 12 patients received TKI therapy after surgery with a mean survival of 26.8 months. The overall survival at 2 and 5 years of nonmetastatic group was 81.1% and 47.5% respectively and in metastatic group was 35.1% and 0%, respectively. Poor performance status, distant metastasis, higher T stage, higher thrombus levels, and positive surgical margins were all predictors of decreased survival. CONCLUSIONS: Complete surgical resection in both nonmetastatic and metastatic RCC with IVC thrombus has long-term survival benefits. Neoadjuvant TKI therapy, with adequate preoperative planning, helps in decreasing the size of the thrombus and in safely avoiding bypass in level III and IV IVC thrombi.

Role of preoperative MR volumetry in patients with renal cell carcinoma for prediction of postoperative renal function after radical nephrectomy and nephron sparing surgery.

PURPOSE: Preoperative computed tomography or magnetic resonance (MR) imaging are commonly used for radiological evaluation of renal cell carcinoma (RCC) before radical nephrectomy or nephron sparing surgery(NSS). This study aimed to assess the role of MRI for predicting postoperative renal function by preoperative estimation of renal parenchymal volume and correlation with glomerular fi ltration rate (GFR). MATERIALS AND METHODS: A prospective observational study was conducted from February 2015 to October 2016 at a tertiary care hospital in northern India. MR imaging was done on 3 Tesla MR scanner (Signa Hdxt General Electrics, Milwaukee, USA). MR volumetry was used to estimate the renal parenchymal volume. GFR was measured in all patients using Tc99m Diethyl-triamine-penta-acetic acid using Russell's algorithm. Such measurement was done preoperatively, and postoperatively 3 months after surgery. RESULTS: 30 patients with suspected RCC underwent NSS (n=10) and radical nephrectomy (n=20). Median tumour volume was 175.7cc (range: 4.8 to 631.8cc). The median volume of the residual parenchyma on the affected side was 84.25±41.97cc while that on the unaffected side was 112.25±26.35cc. There was good correlation among the unaffected kidney volume and postoperative GFR for the radical nephrectomy group (r=0.83) as well as unaffected kidney volume, total residual kidney volume and residual volume of affected kidney with postoperative GFR for the NSS group (r=0.71, r=0.73, r=0.79 respectively; P<0.05). CONCLUSION: Preoperative residual parenchymal volume on MR renal volumetry correlates well with postoperative GFR in patients with RCC undergoing radical nephrectomy or NSS.

Safety and outcome of percutaneous nephrolithotomy in patients with solitary kidney: A tertiary care center experience.

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) for stones in solitary kidney poses a significant challenge and potential threat for acute kidney injury or progression of chronic kidney disease (CKD). We present our experience of PCNL in solitary functioning kidney (SFK) to evaluate the safety, efficacy, and postoperative complications and highlight the differences between these outcomes with respect to the stage of CKD. METHODS: We carried out a retrospective study of patients with SFK, who underwent PCNL at our center from April 2010 to March 2018. Patients who had a minimum of 6 months of follow-up were included. Patients were classified into CKD groups based on the National Kidney Foundation's Kidney Disease Outcomes Quality Initiative. Group 1 included Stages 1, 2, and 3A and Group 2 included Stages 3B, 4, and 5. Postoperative complications and stone-free rate were recorded and graded according to the Clavien-Dindo classification and compared between the two groups. RESULTS: We had a total of 128 patients (Group 1 - 84 and Group 2 - 44). Stone-free rate after the first PCNL was higher in Group 1 as compared to Group 2 (88.1% [n = 74] vs. 50% [n = 22], P = 0.02). Overall, 48 patients (37.5%) had postoperative complications, but most were minor. Clavien Grade 1 and 2 complications were seen in 34 patients (Group 1, n = 18 and Group 2, n = 16, P = 0.069), whereas Grade 3 and 4 complications were seen in 14 patients (Group 1, n = 2 and Group 2, n = 12, P < 0.001), respectively. Need for postoperative (number of sessions) dialysis was seen with increased frequency in patients with higher chronic kidney stages (Group 1 vs. Group 2; 6 vs. 22 sessions, P < 0.001). CONCLUSION: PCNL in SFK is safe, with satisfactory outcome, but patients with advanced CKD stage have higher risk of complications including need for dialysis and may require multiple sessions for complete stone clearance. Hence, they should be managed at high output tertiary centers.

A retrospective analysis of complications of laparoscopic left donor nephrectomy using the Kocak's modification of Clavien-Dindo system.

INTRODUCTION: Kocak described a modification of Clavien-Dindo classification system (CDCS) for reporting procedure-related complications in laparoscopic donor nephrectomy (LDN). We used the Kocak modification in grading and reporting the severity of complications in patients who underwent LDN and in evaluating various parameters that predict them. METHODS: In all, 1430 patients who underwent left LDN from 2000 to 2016 were included in this study. All data was retrospectively collected and analyzed for complications occurring in the postoperative period. All complications were classified according to the four grades of Kocak-modified CDCS. RESULTS: 124 patients (8.6%) suffered a total of 235 postoperative complications. Most of the complications were Grade I and Grade II (Grade I: 79.5% [n = 187] and Grade II 16.2% [n = 38]), 2.5% of the complications were Grade III (n = 6) and Kocak Grade IVa complications occurred in three patients. There was one death (Grade IVb: 0.4%, overall mortality rate: 0.06%). The incidence of complications was significantly greater for male patients, those with body mass index ≥25 kg/m2, and if the operating surgeon had ≤ 1 year of experience in performing LDN surgery. CONCLUSION: LDN is a safe procedure with low morbidity. The rate of complications is 8.6% and most of these complications are of low grade. The use of a standardized system for reporting the complications of LDN allows appropriate comparison between reported data.

Ureterocalicostomy for Reconstruction of Complicated Ureteropelvic Junction Obstruction in Adults: Long-Term Outcome and Factors Predicting Failure in a Contemporary Cohort.

PURPOSE: Ureterocalicostomy is a well established treatment option in patients who have recurrent ureteropelvic junction obstruction with postoperative fibrosis and a relatively inaccessible renal pelvis. We evaluated the long-term outcome of ureterocalicostomy and factors predicting its failure. MATERIALS AND METHODS: We retrospectively analyzed data on 72 patients who underwent open or laparoscopic ureterocalicostomy from 2000 to 2014. Variables that may affect the outcomes of ureterocalicostomy were assessed with regard to primary pathology findings, patient age, serum creatinine, preoperative renal size (less than and greater than 15 cm), renal cortical thickness (less than and greater than 5 mm), hydronephrosis grade and preoperative renal function (glomerular filtration rate less than and greater than 20 ml/minute/1.73 m2). The surgery outcome was calculated in terms of success or failure. Factors predicting failure were evaluated by univariate and multivariate analysis. Failure was defined as an additional procedure required postoperatively due to persistent symptoms and/or followup renal scan showing persistent significant obstruction with deterioration of renal function on at least 2 occasions 3 months apart. Patients with less than 2-year followup were excluded from study. RESULTS: We analyzed data on 72 patients who underwent ureterocalicostomy during this period. Mean ± SD age of the study group was 28.9 ± 12.3 years and mean baseline serum creatinine was 1.1 ± 0.3 mg/dl. The mean glomerular filtration rate was 27.8 ± 11.6 ml/minute/1.73 m2 and mean cortical thickness of the operated kidney was 7 ± 3.86 mm. Common indications for ureterocalicostomy were failed previous pyeloplasty and/or endopyelotomy in 35 patients (48.6%) and secondary ureteropelvic junction obstruction after pyelolithotomy or percutaneous nephrolithotomy in 24 (33.3%). The most common complication was urinary tract infection, which was seen in 22 patients (30.6%). At a mean followup of 60.3 ± 13.6 months 50 patients (69.5%) had a successful outcome. Treatment failed in 22 patients (30.5%), including 6 who required nephrectomy, while 13 were treated with frequent changes of Double-J® stents or with balloon dilation. In 3 patients ureterocalicostomy was repeated. The rate of failed ureterocalicostomy was higher in patients with a low preoperative glomerular filtration rate (less than 20 ml/minute/1.73 m2), attenuated cortical thickness (less than 5 mm) and higher creatinine (greater than 1.7 mg/dl) on univariate analysis. However, on multivariate analysis poor cortical thickness and a low glomerular filtration rate were independent predictors of failure. CONCLUSIONS: Ureterocalicostomy is an acceptable salvage option with a satisfactory long-term outcome. Patients with a low preoperative glomerular filtration rate (less than 20 ml/minute/1.73 m2) and a thinned out cortex (less than 5 mm) showed a poor outcome after ureterocalicostomy.

Multidimensional assessment of quality of life of children and problems of parents in Indian society after pediatric renal transplant: Beyond the conventional thoughts.

This study evaluated multidimensional QoL after renal transplant to find the physical, psychosocial, and economic issues after pediatric transplant. Sixty-two patients under the age of 18 at the time of assessment were asked to complete WHOQOL questionnaires. Assessment of behavioral, emotional status of child, problems of parents, and SEC of family were also performed. The beneficial effect of transplantation was observed across all domains of QoL (physical, psychological, social, environmental, and overall QoL). The greatest change was observed in QoL domains that dealt with overall satisfaction (81.28±15.76 vs 45.32±10.98; P<.0001). The domain dealing with environmental factors showed the least variation after transplantation (65.58±17.45 vs 51.34±17.81; P<.0001). Feelings of happiness and peer group socialization were reported in 81% and 69% of patients, respectively. There was no marital disharmony in 52% of families. However, SEC deteriorated in 16% of families and 59% of the families availed financial assistance. Sixty-nine percent of children had not attended school after one year of transplantation, but return to school after transplant was reduced to 8% at 5 years. Pre- and post-transplant social and psychological support may help these patients and their families adjust in society and have a positive outlook for their future.

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 < 6 months were excluded. Age (≤ and > 65 yr), baseline PSA (< and ≥ 50 ng/ml), bone scan and Gleason score (≤7 and >7) were recorded. Extent of bone disease (EOD) was stratified according to the number of bone lesions i.e., < 5, 5-10, > 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.

Single-centre experience of retroperitoneoscopic approach in urology with tips to overcome the steep learning curve.

CONTEXT: The retroperitoneoscopic or retroperitoneal (RP) surgical approach has not become as popular as the transperitoneal (TP) one due to the steeper learning curve. AIMS: Our single-institution experience focuses on the feasibility, advantages and complications of retroperitoneoscopic surgeries (RS) performed over the past 10 years. Tips and tricks have been discussed to overcome the steep learning curve and these are emphasised. SETTINGS AND DESIGN: This study made a retrospective analysis of computerised hospital data of patients who underwent RP urological procedures from 2003 to 2013 at a tertiary care centre. PATIENTS AND METHODS: Between 2003 and 2013, 314 cases of RS were performed for various urological procedures. We analysed the operative time, peri-operative complications, time to return of bowel sound, length of hospital stay, and advantages and difficulties involved. Post-operative complications were stratified into five grades using modified Clavien classification (MCC). RESULTS: RS were successfully completed in 95.5% of patients, with 4% of the procedures electively performed by the combined approach (both RP and TP); 3.2% required open conversion and 1.3% were converted to the TP approach. The most common cause for conversion was bleeding. Mean hospital stay was 3.2 ± 1.2 days and the mean time for returning of bowel sounds was 16.5 ± 5.4 h. Of the patients, 1.4% required peri-operative blood transfusion. A total of 16 patients (5%) had post-operative complications and the majority were grades I and II as per MCC. The rates of intra-operative and post-operative complications depended on the difficulty of the procedure, but the complications diminished over the years with the increasing experience of surgeons. CONCLUSION: Retroperitoneoscopy has proven an excellent approach, with certain advantages. The tips and tricks that have been provided and emphasised should definitely help to minimise the steep learning curve.

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.

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.

Management of venous hypertension following arteriovenous fistula creation for hemodialysis access.

INTRODUCTION: Venous hypertension (VH) is a distressing complication following the creation of arteriovenous fistula (AVF). The aim of management is to relieve edema with preservation of AVF. Extensive edema increases surgical morbidity with the loss of hemodialysis access. We present our experience in management of VH. METHODS: A retrospective study was conducted on 37 patients with VH managed between July 2005 to May 2014. Patient demographics, evaluation, and procedures performed were noted. A successful outcome of management with surgical ligation (SL), angioembolization (AE), balloon dilatation (BD) or endovascular stent (EVS) was defined by immediate disappearance of thrill and murmur with resolution of edema in the next 48-72 h, no demonstrable flow during check angiogram and resolution of edema with preservation of AVF respectively. RESULTS: All 8 distal AVF had peripheral venous stenosis and were managed with SL in 7 and BD in one patient. In 29 proximal AVF, central and peripheral venous stenosis was present in 16 and 13 patients respectively. SL, AE, BD, and BD with EVS were done in 18, 5, 4, and 3 patients, respectively. All patients had a successful outcome. SL was associated with wound related complications in 11 (29.73 %) patients. A total of 7 AVF were salvaged. One had restenosis after BD and was managed with AE. BD, EVS, and AE had no associated morbidity. CONCLUSIONS: Management of central and peripheral venous stenosis with VH should be individualized and in selected cases it seems preferable to secure a new access in another limb and close the native AVF in edematous limb for better overall outcome.

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.

Follow-up imaging after pediatric pyeloplasty.

INTRODUCTION: The duration, methods and frequency of radiographic follow-up after pediatric pyeloplasty is not well-defined. We prospectively evaluated a cohort of children undergoing pyeloplasty to determine the method for follow-up. METHODS: Between 2000 and 2008, children undergoing pyeloplasty for unilateral ureteropelvic junction obstruction were evaluated for this study. All patients were evaluated preoperatively with protocol ultrasound (USG) and diuretic renal scan (RS). On the basis of preoperative split renal function (SRF), these patients were divided into four groups - Group I: SRF > 40%, Group II: SRF 30-39%, Group III: SRF 20-29%, and Group IV: SRF 10-19%. In follow-up, USG and RS were done at 3 months and repeated at 6 months, 1 year, and then yearly after surgery for a minimum period of 5 years. Improvement, stability, or worsening of hydronephrosis was based on the changes in anteroposterior (AP) diameter of pelvis and caliectasis on USG. Absolute increase in split renal function (SRF) >5% was considered significant. Failure was defined as increase in AP diameter of pelvis and decrease in cortical thickness on 3 consecutive USG, t½ >20 min with obstructive drainage on RS and/or symptomatic patient. RESULTS: 145 children were included in the study. Their mean age was 3.26 years and mean follow-up was 7.5 years. Pre- and post-operative SRF remain unchanged within 5% range in 35 of 41 patients (85%) in Group I. While 9 of 20 patients (45%) in Group II, 23 of 50 patients (46%) in Group III, and 14 of 34 patients (41%) in Group IV exhibited changes >5% after surgery. 5 patients failed, 2 in Group III, and 3 in Group IV. None of the patients deteriorated in Group I and II. CONCLUSION: After pyeloplasty in children with a baseline split GFR >30%, if a diuretic renogram and USG performed 3 months postoperatively shows nonobstructive drainage with t½ <20 min and decreased hydronephrosis, no further follow-up is required.

Trans-vaginal anterior vaginal wall prolapse repair using a customized tension-free bell-shaped prolene mesh: A single-center experience with long-term functional analysis.

INTRODUCTION: The existing literature shows that mesh reinforcement improves the anatomical success rate of cystocele repair. We report the long-term results of a custom bell-shaped mesh with simultaneous urethral support for the repair of cystocele. MATERIALS AND METHODS: The present study was a single-center, single-surgeon case series of 36 patients. Only patients with Pelvic Organ Prolapse Quantification system (POP-Q) stage 2 and above were included in the study. Patients having rectocele or uterine/vault prolapse were excluded. Body of the mesh was used for reinforcement of the cystocele repair and two limbs were left tension free in the retropubic space. Patients were followed 3 monthly for the first year and yearly thereafter. Recurrence was defined as cystocele ≥stage 2 (Aa or Ba 0) any time after the first follow-up. RESULTS: Mean patient age was 58.5 ± 6.2 years. The mean parity was 3.2 ± 1.6. Of 36 patients, 11 (30.5%) of the patients were POPQ stage 2, 15 (41.7%) were stage 3 and 10 (27.7%) were stage 4 cystocele. The mean follow-up period was 53.4 months, with 32 patients reporting for follow-up till date (88.9%). There was no bladder injury, no mesh erosion or infection. No patient required CIC (clean intermittent catheterization) or had stress urinary incontinence post-operatively at 5 years of follow-up. CONCLUSION: The bell-shaped mesh is a simple, effective and safe procedure in the surgical management of cystocele with excellent long-term outcome.

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.

Socioeconomic rehabilitation of successful renal transplant patients and impact of funding source: Indian scenario.

INTRODUCTION: Socio-economic rehabilitation is an important outcome parameter in successful renal transplant recipients, particularly in developing countries with low income patients who often depend on extraneous sources to fund their surgery costs. We studied the socioeconomic rehabilitation and changes in socioeconomic status (SES) of successful renal allograft recipients among Indian patients and its correlation with their source of funding for the surgery. MATERIALS AND METHOD: A cross-sectional, questionnaire-based study was conducted on 183 patients between January 2010 to January 2013. Patients with follow up of at least 1 year after successful renal transplant were included. During interview, two questionnaires were administered, one related to the SES including source of funding before transplantation and another one relating to the same at time of interview. Changes in SES were categorized as improvement, stable and deterioration if post-transplant SES score increased >5%, increased or decreased by <5% and decreased >5% of pre-transplant value, respectively. RESULTS: In this cohort, 97 (52.7%), 67 (36.4%) and 19 (10.3%) patients were non-funded (self-funded), one-time funded and continuous funded, respectively. Fifty-six (30.4%) recipients had improvement in SES, whereas 89 (48.4%) and 38 (20.7%) recipients had deterioration and stable SES. Improvement in SES was seen in 68% patients with continuous funding support whereas, in only 36% and 12% patients with non-funded and onetime funding support (P = 0.001) respectively. Significant correlation was found (R = 0.715) between baseline socioeconomic strata and changes in SES after transplant. 70% of the patients with upper and upper middle class status had improving SES. Patients with middle class, lower middle and lower class had deterioration of SES after transplant in 47.4%, 79.6% and 66.7% patients, respectively. CONCLUSIONS: Most of the recipients from middle and lower social strata, which included more than 65% of our patient's population, had deteriorating SES even after a successful transplant. One-time funding source for transplant had significant negative impact on SES and rehabilitation.

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.

The challenges and outcomes of living donor kidney transplantation in pediatric and adolescent age group in a developing country: A critical analysis from a single center of north India.

INTRODUCTION: Renal transplantation is the treatment of choice for children with end-stage renal disease (ESRD). We evaluated the outcome of renal transplantation in the pediatric and adolescent age groups in the perspective of a developing country as compared with developed nations while highlighting the challenges we have faced in a pediatric transplant programme. MATERIALS AND METHODS: Seventy live related pediatric and adolescent renal transplantations were reviewed retrospectively. Variables analyzed were etiology of ESRD, pre-transplant renal replacement modality, donor relationship, surgical complications, rejection episodes, immuno-suppression regimens, compliance to immunosuppression, graft survival and overall survival. RESULTS: The cohort consisted of 13 (18%) female and 57 male (82%) recipients. The mean age was 14 ± 1.4 years. The etiology of ESRD was chronic glomerulonephritis (n = 43), chronic interstitial nephritis (n = 26) and Alport's syndrome (n = 1). Fifty-six (80%) children were on hemo-dialysis and 10 (14%) on peritoneal dialysis prior to transplantation. 80.5% and 61% patients were strictly compliant to immunosuppresant medications at 1 and 5 years. The 1, 3 and 5 year graft survival rates were 94.3%, 89.2% and 66.8%, respectively. The overall survival rates were 95.7%, 96.4% and 94.1% for 1, 3 and 5 years, respectively. CONCLUSIONS: The spectrum of etiology of ESRD differs in our patients from the west, with chronic glomerulonephritis being the most common etiology. Early graft survival is comparable, but the 5-year graft survival is clearly inferior as compared with developed countries.
