Effect of preoperative finasteride on perioperative blood loss during transurethral resection of the prostate and on microvessel density in patients with benign prostatic hyperplasia: An open label randomized controlled trial.

OBJECTIVE: Transurethral resection of the prostate (TURP) is a common procedure for the treatment of benign prostatic hyperplasia (BPH). Previous studies on the effect of 5-alpha reductase inhibitors on perioperative blood loss in TURP and microvessel density (MVD) in the prostate are equivocal. We evaluated whether pretreatment with finasteride for 2 weeks before surgery can reduce perioperative blood loss in TURP and MVD in the prostate. MATERIALS AND METHODS: Sixty-eight patients of BPH planned for TURP were randomized into two groups. The study group comprising 34 patients was treated with finasteride (5 mg/day) for 2 weeks and the placebo group comprising 34 patients received placebo for 2 weeks, before TURP. Blood loss was measured in terms of a reduction in the blood hemoglobin (Hb) and hematocrit (HCT) levels between preoperative values and 24 h after surgery. MVD was measured in the resected prostate tissue stained with anti-CD31 monoclonal antibody. RESULTS: The reduction of Hb and HCT in the finasteride group was significantly lower than the reduction in the placebo group (P < 0.05). The artery (P = 0.005), vein (P = 0.05), and gland (P = 0.008) densities were significantly less in the finasteride group than in the placebo group. There was no significant correlation between blood loss and MVD. CONCLUSIONS: Our study suggests a clear advantage of the preoperative use of finasteride for 2 weeks by reducing the perioperative blood loss in TURP in patients with BPH. While there is a significant reduction in MVD in the prostate on treatment with finasteride, it is not clear that this is the mechanism of reduction in blood loss in TURP.

Ileal Ureteral Substitution After "Panureteral Damage: A Devastating Complication of Forgotten Double-J Stent".

Background: Forgotten ureteral stent is frequently observed in urologic practice. It has serious consequences such as encrustation, stone formation, fragmentation, ureteral damage, and sepsis. Panureteral damage by forgotten stent is a major complication requiring complex reconstructive surgery. Case Presentation: We report a case of 66-year-old man with forgotten ureteral stent for 10 years, which caused panureteral damage. Ileal ureteral substitution was done and kidney was salvaged. Conclusion: Prolonged forgotten stent can cause panureteral fibrosis and requires complex surgical procedure such as ileal ureteral substitution.

Prospective audit of complications after ultrasonography-guided percutaneous nephrostomy for upper urinary tract obstruction using modified Clavien classification system.

INTRODUCTION: Percutaneous nephrostomy (PCN) is a commonly performed intervention in urology for various benign and malignant conditions causing upper urinary tract obstruction. We present a prospective audit of complications of ultrasonography (USG) guided PCN using modified Clavien classification system (mCCS). METHODS: The data were prospectively collected for 368 PCN performed in 344 patients from June 2015 to January 2017, for various benign and malignant diseases causing upper urinary tract obstruction. Patients were followed for 1 month, and complications arisen of PCN were noted. RESULTS: PCN was successful in 356 renal units. The 12 patients in which PCN failed was due to minimal pelvicalyceal dilatation and PCN was successfully performed after 48 h by a senior urologist. 207 patients had malignant disease and 161 patients had benign condition. Most common malignant disease was carcinoma cervix. 238 were noninfected while 130 had infected renal units. 62 (16.84%) patients had Grade I (self-limiting hematuria/cot/debris/fever). 37 (10.0%) patients had Grade II (7 - transfusion and 30 - urinary tract infection). 34 (9.2%) had Grade III a (repositioning/change/reinsertion of PCN tube under local anesthesia) and 4 (1.1%) had Grade III b (repositioning under anesthesia). 8 (2.2%) Grade IV a (Sepsis), 0 Grade IV b, and 0 Grade V complications were observed. CONCLUSION: USG-guided PCN is a safe, minimally invasive, and effective procedure for upper urinary tract diversion with a low rate of morbidity. Individual complications are within the threshold limits set by the American College of Radiology, the Society of Interventional Radiology. mCCS is well applicable and easily reproducible tool for reporting the complications of PCN.

Laparoscopic Mainz II Approach for Single System Ectopic Ureter with Bladder Agenesis.

Solitary renal unit with ectopic ureter with bladder agenesis is a rare congenital anomaly. Urinary incontinence in such cases is dealt with various continent and noncontinent procedures. We report a case of 20-year-old female patient who presented with continuous leakage of urine. Examination and investigations revealed an absence of right kidney, bladder agenesis, ectopic ureter opening into the vestibule, and multiple bony abnormalities. She was managed effectively by laparoscopic Mainz II with serous lined extramural ureteral reimplantation technique.

Biphasic renal synovial sarcoma with extensive venous tumor thrombosis: A rare presentation.

Primary renal synovial sarcoma (SS) is a very rare soft-tissue tumor arising from the kidney. These tumors histologically closely resemble other sarcoma variants. Immunohistochemical and cytogenetic techniques remain the cornerstone in achieving the correct diagnosis. Radical surgical excision is the primary treatment for local tumor control and alleviation of symptoms. Adjuvant chemotherapy, at present, has only a limited role. We report a unique case of a 21-year-old young male with the diagnosis of a biphasic renal SS with extensive venous system thrombosis involving the inferior vena cava, bilateral iliac, and femoral vessels which was managed by radical nephrectomy and tumor thrombectomy followed by adjuvant chemotherapy.
