Collecting duct carcinoma: A rare renal tumor

The most common primary malignant renal tumor is renal cell carcinoma (RCC), which accounts for 3% of all adult malignancies. Bellini duct carcinoma or collecting duct carcinoma is an unusual rare variant of RCC. This histologically distinct tumor is very rare, with less than 100 cases reported in the literature, and accounts for approximately 1% of all malignant renal epithelial tumors. We report two cases of collecting duct carcinoma and highlight the rarity of these tumors and their similarity to RCC.

Buccal mucosal graft urethroplasty in long segment anterior urethral stricture - Is it gold standard?

To assess the success of dorsal onlay buccal mucosal graft (BMG) urethroplasty in long segment anterior urethral stricture extending from external meatus to bulbar urethra). We studied 40 patients with long segment anterior urethral stricture, who underwent substitution urethroplasty using dorsal onlay BMG from January 2002 to December 2007. The patients were in the age range of 15-65 years (mean 35 years) in the LS group and 16-63 years (mean 34 years) in the non-lichen sclerosus (NLS) group. The cause of stricture was LS in 20 and NLS (inflammatory and idiopathic) in the other 20 patients. The mean stricture length was 14.5 cm (range 12-17 cm) in the LS group while it was 14.0 cm (range 12-16 cm) in the NLS group. The patients were evaluated with antegrade, retrograde urethrograms and sono-urethrograms and they were followed- up with uroflometery at three months for one year, then six- monthly for two years and then annually. The contrast studies were repeated at six-monthly intervals for one year and then annually for one year. Success was defined as normal voiding pattern without any intervention post-operatively. Median follow-up was 48 months (18-72 months) in the LS group, while it was 42 months (12-72 months) in the NLS group. Among the NLS group patients, three patients developed restricture on follow-up, while seven patients among the LS group developed restricture. We conclude that the high percentage of recurrence of strictures (35%) among the LS group renders BMG urethroplasty in long segment anterior urethral stricture an unacceptable solution, and it needs further study.

Synchronous primary cancers of urinary bladder and kidney and prostate

Synchronous occurrence of two or more than two primary cancers of the urinary tract is quite rare, and poses a difficult treatment challenge. Here, we present a case of synchronous renal cell carcinoma, transitional cell carcinoma of urinary bladder and adenocarcinoma of prostate diagnosed within a short period. To the best of our knowledge, this is the first case reported from India and the youngest patient reported in the literature having this combination of urinary cancers.

Renal pleomorphic undifferentiated sarcoma: a rarity.

A 70-year-old male presented with progressive weight loss for eight months. Radiological imaging showed a large tumor in the right kidney. The patient underwent right open radical nephrectomy and histopathology revealed pleomorphic undifferentiated sarcoma (PUS) earlier known as malignant fibrous histiocytoma (MFH). One year after surgery, the patient developed pulmonary metastasis. Unfortunately, the patient died after six months.

Minimally-invasive management of prostatic abscess: The role of transrectal ultrasound

Context and Aim: Prostatic abscess is an unusual condition. The prevalence of prostatic abscess is about 0.5% of all prostatic diseases. The purpose of the study is to present and discuss the role of transrectal ultrasound (TRUS) in the management of prostatic abscess. Settings and Design: Retrospective study. Materials and Methods: We retrospectively reviewed the medical records of all eight patients diagnosed and treated for prostatic abscess in the last threeyears. TRUS was used for diagnosis in all cases. Four patients had TRUS guided aspiration for management of prostatic abscess. Data collected regarding etiology, clinical features, investigations and treatment was compared with the available literature. Results: The age of patients ranged from 18-65 yrs (mean 47.12 yrs). Out of the eight patients, six were diabetics. TRUS revealed one or more hypoechoic areas within the prostate in all the patients. Successful treatment of prostatic abscess with TRUS guided needle aspiration was done in all fourpatients in whom it was used. Mean hospitalization time was 9.4 days, and most frequent bacterial agent was S. aureus. Conclusions: TRUS is useful in diagnosis as well as in guidance for aspiration of such abscesses. TRUS guided needle aspiration is an effective method for treating prostatic abscess. Most of the patients are diabetics and usually grow Staphaureus. So an antibiotic with staphylococcal coverage should be used empirically.

Bilateral single-session retrograde intra-renal surgery: A safe option for renal stones up to 1.5 cm

Introduction: Assessment of treatment outcomes in patients undergoing bilateral single-session retrograde intra-renal surgery (RIRS) for bilateral renal stones up to 1.5 cm. Materials and Methods: Retrospective analysis of 74 patients was done with bilateral renal calculi, who underwent bilateral single-session RIRS at our stone referral hospital from December 2011 to May 2014. The selection criteria for this intervention were patients preference, failure of other treatments and stone up to 1.5 cm. Patients with creatinine more than 2, pyonephrosis sepsis, bilateral impacted pelviureteric junction calculi were excluded from study. All patients were evaluated with serum biochemistry, urinalysis, urine culture, plain radiography of kidney-ureter-bladder, intravenous urography, renal ultrasonography (USG) and/or computed tomography (CT). Follow-up evaluation included serum biochemistry and postoperative plain film and renal USG. The success rate was defined as patients who were stone-free or only had a residual fragment of less than 4 mm. CT was conducted only in patients with residual stones, which were present in seven patients. Results: A total of 74 patients (50 male, 24 female) with a mean age 39.2 ± 15.2 were included in the present study. The mean stone size was 11.7 ± 2.4 mm. The stone-free rates were 86.84% and 97.29% after the first and second procedures, respectively. In eight patients (10.8%), minor complications were observed, whereas no major complications were noted in the studied group. There was no significant difference in pre- and post-operative serum creatinine levels. Conclusion: In patients with bilateral renal stones up to 1.5 cm bilateral single-session RIRS with flexible ureteroscope can be safely performed with low complication rate.

The surgical management of urogenital tuberculosis our experience and long-term follow-up

Introduction: Urogenital tuberculosis (TB) is common in developing countries. We present our experience of surgically managed cases of genitourinary TB (GUTB). Materials and Methods: We retrospectively reviewed 60 cases GUTB who underwent surgery at our center from January 2003 to January 2010. Mode of presentation, organ involvement, investigation, surgical treatment and follow-up were studied. Results: There were 38 males and 22 females with a mean age of 32.5 years. The most common symptom was irritative voiding symptoms. The most common organ involved was bladder in 33 cases, and next most common was kidney in 30 cases. Preoperative bacteriologic diagnosis was confirmed in only 19 cases. A total of 66 procedures were performed as some patients needed more than one procedure. These included 35 ablative procedures and 31 reconstructive procedures. All the patients were followed-up with renal function test (RFT) at 3, 6 and 12 months. The intravenous urography and diethylenetriamine pentaacetic acid scan were performed at 3 months when indicated. Then the patients were followed with RFT and ultrasonography 6 monthly for 3 years and then annual RFT. Conclusion: Many patients of urogenital TB present late with cicatrisation sequelae. Multidrug chemotherapy with judicious surgery as and when indicated is the ideal treatment. The results of reconstructive surgery are good and should be done when possible. Rigorous and long term follow-up is necessary in patients undergoing reconstructive surgery.

Laparoscopic ureteroneocystostomy for management of lower ureteric strictures

Aim: We assessed the results of laparoscopic transperitoneal ureteroneocystostomy with or without a psoas hitch for management of lower ureteral strictures. Materials and Methods: Between October 2005 and August 2008, 16 patients with lower ureteric strictures underwent laparoscopic ureteroneocystostomy with or without a psoas hitch. Etiology of strictures was gynecological surgery in 11, surgery for stone disease in 3, ureterovaginal fistula in 1 and primary obstructive megaureter in 1. Transperitoneal 3- or 4-port laparoscopic ureteroneocystostomy was performed with or without psoas hitch. Results: All operations were successfully completed without any need for conversion to open. Mean operative time was 171.56 min (range 130 to 260 min), mean blood loss was 93.44 cc (range 30 to 200 cc) and total hospital stay was 3.73 days (range 3 to 6 days). Mean time to resume oral intake was 12.5 h (range 8 to 22 h). Mean follow-up period was 21.83 months (range 6-39 months). Postoperative follow-up investigations revealed successful outcome in all 16 patients, success being defined as relief of symptoms and radiological improvement, irrespective of the refluxing status. Non-refluxing status was achieved in 15 out of 16 patients as determined by micturition cystography. Conclusions: Laparoscopic ureteroneocystostomy is a safe and effective procedure, with inherent advantages of laparoscopic surgery.
