  • Polyps of the male urethra are relatively uncommon lesions. They usually arise from the prostatic urethra mostly verumontanum or Just lateral to the verumontanum. Posterior urethral polyp often presents with hematuria, hemospermia and sometimes lower urinary tract obstruction. We recently experienced a pedunculated prostatic urethral polyp in a 63-year-old man who complained of gross total hematuria and difficult micturition for several years. On rectal examination the prostate was slightly enlarged with normal consistency. Excretory urogram showed a round filling defect in the right side of the bladder neck measuring about $2{\times}2cm.$ in size. Cystourethroscopy revealed trabeculation of the vesical wall, mild bilateral prostatic hypertrophy and a round cystic mass with a long stalk arising from the prostatic floor 1 cm. Proximal to the verumontanum which caused ball-valve obstruction in the bladder neck. This pedunculated polypoid mass was then resected at its base with resectoscope and was removed transurethrally using Lowsley's grasping forceps. The specimen was proved as fibrous polyp histologically.

  • Bilateral renal obstruction is a rare critical condition, requiring a prompt diagnostic approach and treatment to restore the renal function. The most commonly observed obstructive uropathy in children is congenital malformation, such as posterior urethral valves and bilateral ureteropelvic junction obstruction. Malignant pelvic masses obstructing the ureter are widely reported in adults but are rarely observed in children. The treatment of ureteral obstruction related to pelvic malignancy is a therapeutic challenge with a median survival duration of 3-7 months in adults; however, pediatric patients with pelvic malignancy leading to ureteral obstruction had better outcomes, with a reported 5-year mortality rate of 20%, than the adult patients. Here, we report a rare case of bilateral ureteral obstruction associated with pelvic rhabdomyosarcoma presenting with acute kidney injury treated by ureteral diversion with double J stent, and concommittent emergency hemodialysis, leading to restoration of good renal function. We suggest that bilateral ureteral obstruction should be released as soon as possible using surgical or interventional approach to minimize the obstruction period, and subsequential chemotherapy may contribute to improvement of survival and recovery of renal function.

  • We present a case of a 47-month-old female suffering from acute urinary bladder neck obstruction and bilateral hydronephrosis secondary to a fecaloma. Fecaloma is defined as an accumulation of inspissated feces in the colon or rectum giving the appearance of an abdominal mass. A fecaloma can be developed by diverse causes and the causes of the fecaloma in this case were septum reformation after the Duhamel procedure and long-term constipation. Chronic constipation is very common at outpatient clinic. However, acute urinary retention and voiding difficulty caused by fecaloma in the giant Duhamel pouch has never been reported in Korea. We would like to present our case with acute urinary retention due to a fecaloma and suggest that fecaloma might be considered as one of the causes for acute urinary retention, especially in cases with previous Duhamel operation for repair of Hischsprung disease.

  • Purpose: We compared a transperineal ligation model and a transperitoneal ligation model in male rats to determine which animal model of overactive bladder (OAB) was more useful based on cystometrography, estimations of oxidative stress, and measurements of pro-inflammatory cytokine levels. Materials and Methods: Male rats were randomly divided into three groups (n=15 in each): the control group, the transperineal ligation group, and the transperitoneal ligation group. Four weeks after the ligation procedure, cystometrography was performed and oxidative stress, pro-inflammatory cytokine levels, and histologic changes were evaluated. Oxidative stress was assessed by measuring 8-hydroxy-20-deoxyguanosine and superoxide dismutase, and pro-inflammatory cytokine activity was investigated by measuring levels of interleukin (IL)-6, IL-8, and tumor necrosis $factor-{\alpha}$. Results: The transperineal model led to results similar to those observed for the transperitoneal model, namely (1) increased voiding frequency and reductions in the non-voiding contraction interval and the maximal vesical pressure, (2) increased levels of oxidative stress markers, (3) increased pro-inflammatory cytokine levels, and (4) fibrotic changes in the bladder tissue. Conclusions: We suggest that the transperineal procedure can be used as an alternative OAB model in male rats.

  • A case of severe complications following intrathecal administration of 45 ml of hypertonic saline solution for the treatment of postherpetic neuralgia was presented. Transient immediate complications included were tachycardia, hypertension, neck stiffness and muscle twitch. Pulmonary edema, paralytic intestinal obstruction, and the cauda equina syndrome including sphincter disorder with atonic urinary bladder developed shortly after the injection. Tenesmus and sensory abnormality around perineum and soles were the longlasting complications.
