Transurethral Needle Ablation of BPH / 대한비뇨기과학회지

PURPOSE: Transurethral resection of prostate(TURP) is the gold standard for the treatment of benign prostate hyperplasia(BPH) at the present. But many attempts have been made to develop minimally invasive method. We studied the efficacy of transurethral needle ablation(TUNA) of prostate for treatment of BPH. MATERIALS AND METHODS: We performed TUNA in 20 BPH patients including 13 patients with acute urinary retention. Preoperatively all patients were evaluated using urinary flow rates, International Prostate Symptom Score(1-PSS), Quality of life and cystoscopic examination. The urinary flow rates, 1-PSS and Quality of life were checked at 1, 3 and 6 months after TUNA in all patients. RESULTS: The average value of peak flow rate of the patients with urinary retention were 10ml/sec, 12ml/sec and 13ml/sec at 1, 3 and 6 months follow-up. The average value of Qmax of the patients without urinary retention were 9ml/sec preoperatively and increased to 13ml/sec, 13ml/sec and 14ml/sec at 1, 3 and 6 months postoperatively. 1-PSS of patients with urinary retention improved from average 26 at preoperation to 14, 13, 10 at 1, 3 and 6 months postoperatively. Quality of life of patients with urinary retention improved from average 5 at preoperation to 2, 2, 2 at 1, 3 and 6 months postoperatively. The average value of patients without urinary retention improved from average 26, 5 at preoperation to 14, 11, 11 and 2, 2, 2 at 1, 3 and 6 months follow-up. No patients complained of erectile dysfunction and retrograde ejaculation postoperatively. CONCLUSIONS: The result of our preliminary study suggest that TUNA can be considered to be a simple, safe and efficacious procedure for the treatment of BPH including urinary retention.

A Case of Tuberculous Infection of Renal Cyst / 대한비뇨기과학회지

Tuberculous infection of renal cyst is a very rare disease. We report a case of tuberculous infection of renal cyst in a 31 years old man. Incidental renal ultrasonography showed multiple septated cysts on the upper pole of the left kidney. Abdominal CT showed septated left renal cyst with calcification. The patient was treated with cyst aspiration and unroofing. AFB were confirmed in the culture of aspirated fluid of renal cyst. Pathologic examination revealed chronic granulomatous pyelonephritis with caseous necrosis.

A Case of Verrucous Carcinoma of Renal Pelvis / 대한비뇨기과학회지

Verrucous carcinoma is a form of low grade squamous cell carcinoma that is characterized grossly by its exophytic and wart-like appearance. We experienced a case of verrucous carcinoma in a 63-year-old female patient who presented with pyelonephritis caused by staghorn calculi. Abdominal CT scan showed a renal pelvic mass and nephrectomy was done. Histologic examination showed extensive keratinizing squamous metaplasia of pelvic urothelium with an area of verrucous acanthosis. To our knowledge, this is the second case of verrucous carcinoma of renal pelvis that has been reported in literature. We describe a case and review the literature concerning verrucous carcinoma.
