RESUMO
BACKGROUND: The prevalence of stress urinary incontinence (SUI) in the middle-aged Indian women is around 16%. The use of transvaginal tapes (TVTs) has revolutionised the surgical management of SUI. Patients who undergo placement of the tape via the transobturator route often complain of persistent thigh pain at the site of trocar insertion. The use of minimally invasive tapes with a single suburethral incision reduces surgical trauma by eliminating thigh incisions, while maintaining the cure achieved by conventional TVTs. The study was conducted to test the efficacy and safety of minimally invasive TVT-Secur tape placement for treatment of SUI in women. METHODS: 20 women with stress incontinence were implanted with TVT-Secur tapes and followed up for a year. RESULTS: The objective cure rate of SUI was 85% at the end of a year. The improvement in the patient satisfaction and Incontinence-specific QOL scores, of both Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7), was statistically significant at 95% and 99% confidence levels. There were no complaints of thigh pain; however, there were intraoperative complications in the form of bladder perforation in 5% (n = 1), urethral injury in 5% (n = 1) and urethral tape exposure in 10% (n = 2), at 3 months requiring tape sectioning. CONCLUSIONS: These cure rates and complications are comparable to the standard TVT implantations at the end of a year, without thigh pain; however, a greater number of patients and a longer follow-up is required to see whether the long-term cure is maintained or not, before recommending the same as a standard of treatment.
RESUMO
Many studies have been done to determine the risk factors associated with urolithiasis so that preventive measures can be undertaken to prevent stone formation. However the exact aetiology of urinary stones still remains elusive. A prospective control study of epidemiological factors that influence urinary stone formation was done to determine the aetiology of urinary stones. Patients with stone disease had a significantly higher body mass index. 24-h urine excretion of uric acid and phosphate was found to be significantly higher in stone patients as compared to controls. The intake of non-vegetarian food was significantly higher amongst stone formers. Stone patients had a significantly higher consumption of curd and cheese as compared to controls. There was a significant correlation noted between stone formation and a positive family and past history of stone disease. The results indicate that obese patients, especially those with a family history of stone disease, should be counselled on weight loss. Individuals with a past history of stone disease should be advised to reduce their dietary intake of foods rich in uric acid (meat, liver and beans).

BACKGROUND: This study was carried out to assess the spectrum of renal and perinephric space infection among urology patients admitted in the last three years. METHODS: Medical records of patients with renal and perinephric abscess and emphysematous pyelonephritis were reviewed. RESULTS: Out of 2278 patients admitted in last three years, 29 (1.2%) patients suffered from renal and perinephric space infection, 13 (45%) patients had renal abscess, 11 (38%) perinephric abscess and five (17%) emphysematous pyelonephritis. Sixteen (55%) patients recovered conservatively, nine (31%) patients required percutaneous drainage of the abscesses and remaining four (14%) underwent surgical exploration. The overall mortality was 14% in this study. CONCLUSION: Renal and perinephric space infection continues to be a serious urological problem with high mortality rate. A high index of suspicion, prompt diagnosis, appropriate antibiotics and surgical intervention may be effective in reducing mortality.
RESUMO
BACKGROUND: Renal transplantation is the treatment modality of choice for patients with end stage kidney failure. We present our experience of graft and patient survival of initial 500 renal transplants performed between May 1991 and July 2006, at Army Hospital (R&R). MATERIAL AND METHODS: All patients received triple drug immunosuppression with cyclosporine/tacrolimus, azathioprine/ mycophenolate mofetil and steroids. Patients in high risk group received induction therapy with IL-2 receptor blockers/anti-thymocyte globulin. RESULTS: Majority of the recipients (79%) were males, whereas majority of the donors (59.4%) were females. In the donor profile, 385 (77%) transplants were live related, 108 (21.6 %) were spousal and 7 (1.4%) were cadaveric transplants. Mean age of the donors and recipients was 42.11 ± 11.53 years (range 19-72 years) and 33 ± 9.39 years (range 5-60 years) respectively. Eighty two patients (16.4%) were lost to follow up and the present data on rejections, patients and graft survival pertains to 418 patients. These patients have been followed up for a mean period of 2.63 years (SE, 0.122; median 1.8 years; range 0-13.36 years). Acute rejection episodes occurred in 115 (27.3%) patients and 95% of these could be reversed with steroids/ATG. Sixty eight patients (16%) have died on follow-up. Our one-year, 5 year and 10 year estimated graft survival is 95.4% (SE, 0.01), 80.5% (SE, 0.03) and 53.1% (SE, 0.09) respectively and patient survival at one year is 93.2% (SE, 0.01). The estimated graft and patient survival in our series is 9.83 (95% CI, 8.92-10.73) and 9.80 (8.93-10.67) years respectively. CONCLUSION: This centre's short-term graft survival of 95.4% is comparable to the best centres of the world.
RESUMO
BACKGROUND: Laparoscopic donor nephrectomy (LDN) has been gaining popularity among kidney donors. There have been concerns about the safety and efficacy of the procedure as compared to open donor nephrectomy (ODN). We compare our results on LDN with ODN. METHODS: We retrospectively analysed our data of LDN and ODN. Duration of surgery, blood loss, period of hospitalisation, per oral intake and analgesic requirements. RESULT: 22 LDNs were done, the operation time ranged from 220-300 minutes, and blood loss from 100-150ml. In the first 10 laparoscopic operations four cases required conversion to open surgical dissection. Only one case was converted to open surgery in the subsequent 12 laparoscopic cases. Oral intake was started on the first postoperative day. Analgesic requirement in laparoscopy cases was less. Patients were mobilised on the first day after surgery. Patients were discharged by seventh day. There was no significant difference in the functioning of the graft after revascularisation in the recipient. CONCLUSION: Laparoscopic donor nephrectomy is a safe and effective technique of donor nephrectomy.
RESUMO
A 35-year-old man with left lower ureteric stone underwent ureteroscopic stone removal. Holmium: YAG laser lithotripsy was used to break the stone and to remove a larger fragment a 3 Fr. steel wire stone basket was introduced through the ureteroscope. However, during removal the basket with the stone became impacted in the intramural part of the ureter. All attempts to dislodge the stone and the basket failed. Laser fiber was introduced through the second channel of the ureteroscope bridge and the laser activated at settings of 0.5J and 10Hz. Pulverization of the stone did not free the basket and hence 2 wires of the stuck basket were cut with the laser. This enabled the basket to be freed and easily removed.

Bardet-Biedl syndrome (BBS) is a rare cause of renal failure requiring renal replacement therapy. It is an autosomal recessive condition characterized by retinitis pigmentosa, postaxial polydactyly, central obesity, mental retardation, hypogonadism, and renal involvement. We report the first successful renal transplant in a case of BBS from India.
RESUMO
OBJECTIVES: The sensitivity of voided urinary cytology has been reported as very low. In this study, we investigated the sensitivity and clinical utility of voided urinary cytology in the detection of various grades and stages of transitional cell carcinoma (TCC) of the bladder compared with the urinary nuclear matrix protein-22 (NMP-22) qualitative assay. METHODS: From March 2004 to April 2006, all patients with TCC of the bladder receiving follow-up care and those presenting with gross hematuria were enrolled in this prospective study. These patients underwent urinary cytologic examination and NMP-22 qualitative assay. The diagnosis, determined from the cystoscopy findings and biopsy findings of the suspicious lesion, was accepted as the reference standard. RESULTS: A total of 196 patients were enrolled in this study, of whom 127 patients had previously been diagnosed with bladder TCC and 69 were presenting for investigation of gross hematuria. A total of 52 cases of bladder TCC were diagnosed. The overall sensitivity of voided urine cytology and NMP-22 assay was 21.1% and 67.3%, respectively (P <0.001). The sensitivity of urinary cytology and urinary NMP-22 for well-differentiated tumors was 9.5% and 52.4%, respectively, and was 18.1% and 77.3%, respectively (P <0.001), in moderately differentiated tumors. The overall specificity of urinary cytology for TCC of the bladder was 98.6% and was greater than the specificity of NMP-22 (80.5%). CONCLUSIONS: The results of our study suggest that urinary cytology has a very low sensitivity and can be omitted in favor of NMP-22 in the follow-up of low-grade superficial bladder TCC.

Laparoscopic adrenalectomy (LA) is now the gold standard for the treatment of small, benign adrenal tumors in adults. In Cushing's syndrome (CS), LA is difficult and seldom done, especially in younger children. A 6-year-old girl was diagnosed with CS due to a juxtaadrenal tumor. She underwent LA and made an uneventful recovery. The histopathology was reported as paraganglioma which is a very rare cause of CS. LA is seldom done in younger children with CS owing to extreme obesity, abundant perinephric fat and a high incidence of pre- and postoperative complications.

Intravesical explosion during transurethral resection of the prostate (TURP) is an extremely rare but dreaded complication and results in rupture of the bladder. It is believed that intravesical explosion occurs due to formation of explosive gases in the bladder during TURP and its admixture with air. A case of intravesical explosion during TURP resulting in bladder rupture at our institution is described. Though the management of this catastrophe is relatively straightforward, it has the potential for dire consequences. We emphasize that, despite its rare occurrence, it is preventable and suggest measures to avoid it.

The objective was to determine the efficiency of extracorporeal shockwave lithotripsy (ESWL) in clearing stones from renal units with impaired function. Thirty-five patients with poorly functioning kidneys determined by intravenous urogram and 99mtechnetium diethylene triamine pentacetic acid renal dynamic scan underwent ESWL. Stone clearance was assessed at 3 months and compared with that in normally functioning kidneys. The study group was divided into two subgroups. Those with split glomerular filtration rate (GFR) of the concerned kidney between 10 and 20 ml/min were in group 1. Group 2 consisted of patients with split GFR between 20 and 30 ml/min. A control group (group 3) was formed from patients with urolithiasis and normally functioning kidneys. The overall retreatment rate was 84.4%. The overall stone clearance rate in the study group was 34.2% while it was 57.7% in the control group. The stone clearance rate in group 2 was 40%. The difference in stone clearance rate between the study and control groups was statistically significant (P=0.023) but that between group 2 and the control group was not (P=0.159). The incidence of steinstrasse between the study group 2 and control group was not statistically significant (P=0.408). The clearance rate for ureteral stones was comparable in all the three groups. The stone-free rate and rate of steinstrasse for renal stones in kidneys with moderately impaired function were comparable to normally functioning kidneys. However, kidneys with severely impaired function had poor results. The clearance rate for ureteral stones was not influenced by the impairment of renal function.

BACKGROUND: This study is a retrospective analysis of urological complications and their treatment in our series of live-donor renal transplantation. MATERIAL AND METHODS: The series comprised of 500 patients. All underwent extravesical ureteroneocystostomy and all except a few initial patients were stented. RESULTS: There were 92 complications in 82 patients (18.4%). Urinary leakage occurred in 1.2%. There were no intrinsic ureteric obstructions. Extrinsic ureteric obstruction occurred in 0.8% of cases. The incidence of UTI was 15.4% and of urethral strictures 1%. CONCLUSION: The technique of stented extravesical ureteroneocystomy has led to an extremely low rate of urological complications in our series, over a long time and in a substantial number of patients.

OBJECTIVES: To analyze donor and recipient outcome of grafts from marginal kidney donors (ie, elderly or suffering from some anomaly). METHODS: We had 81 marginal donors from July 1996 to July 2004; 46 were older than 60 years, and 39 had renal or nonrenal anomaly. The donors and recipients were evaluated for morbidity, graft and recipient survival, and the number of rejection episodes. RESULTS: The mean (+/- standard deviation) age of elderly donors was 62.2 +/- 3.1 years. Follow-up ranged from 6 months to 50 months (mean 21.15 +/- 0.9 months). Actuarial 1-year and 3-year graft survival rates were 95% and 81%, respectively. Twenty-six percent of recipients maintained serum creatinine levels less than 1.4 mg/dL. The mean age of hypertensive donors was 46.2 years, and blood pressure was controlled with one drug. Serum creatinine levels in the recipients were less than 1.4 mg/dL in 10 and less than 2.5 mg/dL in the rest. Eleven percent of hypertensive donors required an increase in their antihypertensive medication. All donors showed a 15% to 20% increase in their glomerular filtration rate. Donors underwent simultaneous surgery when indicated. CONCLUSIONS: Criteria to reject donors need to be reviewed periodically. The elderly and donors with other anomalies are consistently showing acceptable results. Hypertensive donors require assessment with awake ambulatory blood pressure monitoring.

Spontaneous perirenal hematoma (SPH) is a clinical entity that poses a diagnostic and therapeutic challenge. We report a case of SPH in an adult where the cause could not be determined at first presentation, even with computed tomography (CT) of the abdomen and angiography. He was under close follow-up, and it was only with a repeat CT scan after 3 months that a mass lesion in the kidney was identified as the underlying cause. We also present a review of the literature so that a logical approach can be adopted for this problem.

A 32-year-old lady presented with primary infertility and a 1-year history of recurrent left-flank pain. She was found to have left lower ureteric obstruction on intravenous urography. No specific cause for the obstruction could be determined preoperatively. The patient underwent open extraperitoneal surgery to determine the cause and to treat the obstruction. A 4-mm vessel was seen crossing over the ureter at the site of narrowing. It was the persistent umbilical artery traced in continuity from the internal iliac artery. The vessel was resected, and the ureter was reimplanted into the bladder. Extrinsic obstruction of the distal ureter because of aberrant or persistent vessels has been infrequently reported. Such reports predominantly refer to children, and the diagnosis is usually made at laparotomy, frequently following previous failed attempts at endourological management.
