Urinary incontinence following transurethral prostatectomy presenting as self inflicted penile gangrene.

An elderly diabetic man with a 67 g prostate developed a moderate degree of stress urinary incontinence along with urge urinary incontinence after transurethral resection of the prostate. Initially, he did not perform the recommended pelvic floor exercise and wrapped a rubber band around his penis to control the problem. He presented with late development of penile gangrene requiring partial amputation of his penis. The stress urinary incontinence subsided on subsequent follow-up. The patient is now doing well.

Evaluation of stone-free rate using Guy's Stone Score and assessment of complications using modified Clavien grading system for percutaneous nephro-lithotomy.

To prospectively evaluate the ability of Guy's Stone Score (GSS) in predicting stone clearance rate and complication rate (by modified Clavien grade) for renal stones treated by percutaneous nephrolithotomy (PNL). From January 2013 to June 2014, a total of 142 patients undergoing PNL were evaluated prospectively. Patients with co-morbidities like hypertension, diabetes, renal failure were excluded from the study. All patients were classified according to GSS based on the findings of pre-operative intravenous urography (IVU) and per-operative retrograde pyelography (RGP). All PNL procedures were done by standard technique in prone position and success was defined as no residual stone visible on X-ray KUB done on the third postoperative day. Complications were classified according to modified Clavien grading system. The initial stone clearance rate was 71.1% and overall final stone clearance rate was 90.14%. The complication rate according to Clavien grading system was 40.1%. The final stone clearance rates were 93.9, 85.71, 90.47, and 77.77% in GSS I, II, III, and IV, respectively (p<0.001, <0.05, <0.05 and >0.05, respectively). The Clavien complication rates were 23, 61, 52, and 77.7% in GSS I, II, III, and IV, respectively (p<0.001). The GSS is a simple and easily reproducible system to preoperatively predict stone-free rate and perioperative complication rate. It helps in better patient counseling preoperatively.

Transrectal ultrasonography (TRUS)-guided pelvic plexus block to reduce pain during prostate biopsy: a randomised controlled trial.

OBJECTIVE: To assess the role of pelvic plexus block (PPB) in reducing pain during transrectal ultrasonography(TRUS)-guided prostate biopsy, compared with the conventional periprostatic nerve block (PNB). PATIENTS AND METHODS: A prospective, double-blind observational study was conducted with patients being randomised into three groups. Group-1 (47 patients) received intrarectal local anaesthesia (IRLA) with 10 mL 2% lignocaine jelly along with pelvic plexus block (PPB) with 2.5 mL 2% lignocaine injection bilaterally. Group-2 (46 patients) received IRLA with periprostatic nerve block (PNB). Group-3 (46 patients) received only IRLA without any type of nerve block. The patients were requested to rate the level of pain from 0 to 10 on a visual analogue scale (VAS) at two time points: VAS-1: during biopsy procedure and VAS-2: 30 min after the procedure. RESULTS: The mean age of the patients, mean volume of the prostates and mean serum PSA values were comparable among the three groups. The mean pain score during biopsy was significantly less in the PPB group [mean (range) sore of 2.91 (2-4)] compared with the PNB group [mean (range) score of 4 (3-5)], and both these groups were superior to the no nerve block group [mean score of 5.4 (3-7)]. There was no significant difference between the mean pain scores, 30 min after the procedure among the three groups with the mean (range) scores being 2.75 (2-4), 2.83 (2-4) and 2.85 (2-4), respectively. CONCLUSION: PPB is superior to conventional periprostatic nerve block (PNB) for pain control during TRUS-guided biopsy and both are in turn superior to no nerve block.

Analysis of urinary stone composition in Eastern India by X-ray diffraction crystallography.

BACKGROUND: Stones in the urinary system are common in our country. This study was done to assess the composition of the urinary stones in eastern part of India. MATERIALS AND METHODS: A prospective study was done over a period of thirty months. A total of 90 stones were analyzed in this time period by using X-ray diffraction crystallography. RESULTS: Of the 90 stones analyzed, 77 were renal stones, 12 were ureteric stones and one was a bladder stone. Six stones (all renal) did not have properties to be represented by X-ray diffraction crystallography. The overall prevalence of the oxalate containing stones was 85.7% with calcium oxalate monohydrate (COM) being the major constituent. Calcium oxalate dihydrate (COD) was the next most common constituent. Struvite stones constituted 9.5% of the stones analyzed. Pure calcium phosphate stones were found in 4.7% of the cases. CONCLUSION: Our study reveals that the stone composition in the eastern part of India is different from that in other parts of the country. We have a comparatively lower prevalence of oxalate stones while a higher prevalence of phosphate and struvite stones.
