Extravaginal neonatal testicular torsion, although it is rare, is being recognized with increasing frequency. Furthermore, bilateral neonatal torsion is very uncommon. Because of the seriousness of the outcome due to the risk of future anorchia, this condition that requires prompt recognition and careful decision making. We experienced a case in which the patient had bilateral neonatal testicular torsion and the patient showed bilateral necrotized testes during operation. However, the histopathologic findings during operation showed a small intact portion only in the left testis. Right orchiectomy and left orchiopexy were performed, and the left testis was saved. We report here on this case with a review of the literature.

Sarcoidosis is an idiopathic, multisystem disease that rarely involves the genitourinary tract. Here we present an unusual case of testicular sarcoidosis with extensive lymphadenopathy that mimicked a metastatic testicular tumor. A 27-year-old male presented with a palpable right testicular mass accompanied by multiple palpable inguinal lymph nodes. The scrotal ultrasound showed a hypoechoic lesion at the inferior portion of the right testis. Extensive enlarged lymph nodes were noted in multiple areas on the abdominal computed tomography. Preoperative testicular tumor markers were within the normal range. Exploration of the right testis with a frozen section analysis of the right testicular mass and of a palpable right inguinal lymph node showed granulomatous inflammation. The testis was salvaged and the final pathological diagnosis was sarcoidosis. Treatment with high-dose corticosteroids resulted in complete resolution of the intratesticular mass and a significant decrease in the extent of the lymphadenopathy.

Sarcoma of the kidney is a rare condition. Leiomyosarcoma is the most common of the kidney sarcomas. Renal leiomyosarcoma usually originates from the smooth muscle layers of the kidney, for example, the renal capsule and renal vessels. Renal pelvis neoplasms, however, are primarily transitional cell carcinomas, and renal pelvis leiomyosarcomas are extremely uncommon. Renal pelvis leiomyosarcoma has never been reported in Korea. Moreover, no more than 10 cases have been reported internationally. However, none of these were associated with kidney abnormalities. Here we describe a case of leiomyosarcoma that originated from the blind end of a bifid renal pelvis.

PURPOSE: We assessed the accuracy of urinary detection by visualization compared with a method using the urethral channel of a transurethral, three-channel urodynamic catheter. MATERIALS AND METHODS: This was a case series of 52 patients presenting with stress urinary incontinence over 2 years. Patients underwent video-urodynamic studies in both the supine and the erect positions by use of two techniques for measuring leak point pressure (LPP) by one examiner. LPP was determined as the intravesical pressure simultaneous to the starting point of urethral pressure changes through the urethral channel of a urodynamic catheter (LPP-ure) and then by visualization (LPP-vis) during different events. We also measured the time related to the provocations and the time to mark the leakage on the urodynamic machine by the examiner. RESULTS: The LPP-ure values (cough supine: 42.1+/-18.7, cough erect: 42.1+/-21.8, Valsalva supine: 42.2+/-23.3, Valsalva erect: 41.0+/-22.6 cmH2O) were significantly lower than the LPP-vis values (89.9+/-29.4, 97.4+/-30.4, 70.6+/-25.2, and 74.4+/-32.6 cmH2O, respectively, all p<0.001). Whereas the actual leakages happened during the pressure increases, urodynamic recording by visualization was done after those increases had finished. CONCLUSIONS: The use of visualization as a urinary detection method entails potential errors that cannot be adjusted for on that time scale. Our results emphasize the need to standardize the methodologies used for urinary leakage detection, because this measurement is closely related to the accuracy of measurement of leak point pressure.

Spontaneous rupture of the renal pelvis or ureteropelvic juction area with extravasation of urine into the perinephric space is an uncommon pathologic condition (1). We report a case of 72-year-old woman who suffered 2 days of left loin pain. The patient has got residual urine sensation and weak urine stream since she has gone through a radical hysterectomy 17 years before. Because of these symptoms of voiding difficulty, the patient had abdominal straining during her urination. A CT scan exhibited renal pelvis rupture with perirenal extravasation of urine due to severe hydronephrosis, that was exacerbated by hidden neurogenic bladder disease. Moreover, the patient has detrusor underactivity and high intravesical pressure at voiding trial in the urodynamic study. One month after the percutaneous nephrostomy insertion into the left renal pelvis, the patient was successfully treated. The size of renal pelvis decreased. Moreover, urinoma disappeared in follow up CT scan image.

PURPOSE: We aimed to evaluate the efficacy of warm water sitz baths in patients who have undergone transurethral resection of the prostate (TURP) owing to lower urinary tract symptoms secondary to benign prostatic hyperplasia. MATERIALS AND METHODS: We reviewed the records of 1,783 patients who had undergone TURP between 2001 and 2009. In the warm water sitz bath group, patients were instructed to sit in a tub containing lukewarm water at 40-45degrees C for 10 minutes each time. Patients were advised to perform the procedure for at least 5 days immediately after the removal of a Foley urethral catheter. The differences in post-TURP complications between the warm water sitz bath group and the no sitz bath group were compared. RESULTS: After TURP, 359 of the 1,561 patients performed a warm water sitz bath. Complications after TURP, such as hemorrhage, urinary tract infection, urethral stricture, and acute urinary retention were found in 19 (5.3%) and 75 (6.2%) patients in the sitz bath and no sitz bath groups, respectively (p=0.09). There was a significant difference in postoperative complications such as urethral stricture between the warm sitz bath group and the no sitz bath group (p=0.04). The group that did not undergo warm water sitz bath treatment showed a 1.13-fold increased risk of rehospitalization within 1 month after TURP due to postoperative complications compared with the warm water sitz bath group (odds ratio [OR]=1.134; 95% confidence interval [CI], 1.022 to 1.193; p=0.06). CONCLUSIONS: Warm water sitz bath treatment reduced postoperative complications such as urethral stricture. These results suggest that large-scale prospective studies are needed to establish an ideal method and optimal duration of sitz baths.

Basal cell carcinoma (BCC) of the prostate, a rare variant of prostate cancer, is derived from the basal cells of prostatic ducts and acini. BCC generally occurs in elderly men with obstructive voiding symptoms and levels of serum prostate-specific antigen within the normal range. In most cases, diagnosis is made through transurethral resection or simple enucleation. Most cases are indolent, but local recurrence and metastasis have been reported in a few cases. Thus, radical surgery and long-term follow-up are recommended. We report a case of a 54-year-old man who underwent radical retropubic prostatectomy after being diagnosed with BCC during a transurethral resection performed for lower urinary tract symptoms. The patient has remained free of disease for 4 months after surgery.

PURPOSE: We have previously demonstrated that increased urethral resistance was more prominent in diabetic rats than in controls. This may result from a compressive obstruction such as damage of the urethral nerve containing nitric oxide. Another possible cause for urethral obstruction could be a constrictive obstruction such as a periurethral fibrosis. In the present study, we investigated the changes in the expression of nitric oxide synthase(NOS) isoforms(compressive obstruction) and collagen subtypes (constrictive obstruction) in the urethral tissues of non-insulin dependent diabetic rats. MATERIALS AND METHODS: Thirty-six male Sprague-Dawley rats(18 diabetic rats and 18 control rats), bred from birth, were included in this study. Diabetes mellitus was induced by intraperitoneal administration of streptozotocin(90mg/kg) on the second day after birth. Urethral tissues were harvested at 12, 24 and 36 weeks after induction of diabetes and were stained for neuronal NOS(nNOS) and Masson trichrome. We also performed reverse transcriptase-polymerase chain reaction or Western blot analysis to evaluate mRNA or protein expression of NOS isoforms and collagen subtypes in the urethral tissues. RESULTS: Immunohistochemical staining and Western blot analysis of nNOS revealed that the immunoreactivity and nNOS expression in the urethra was lower in the diabetic rats than in the controls. The Masson trichrome staining showed that there was urethral fibrosis in the diabetic rats. The mRNA or protein expression of collagen subtypes, especially type I collagen, were higher in the diabetic rat urethra than in the controls. CONCLUSIONS: These data suggest that the increased urethral resistance in diabetic rats may be attributable to a decrease in the urethral nNOS expression and an increase in collagen content. Urethral dysfunction as well as a cystopathy may play an important role in the pathogenesis of diabetes- induced voiding dysfunction. (Korean J Urol 2007;48:1050-1057)

Lymphoproliferative disorder in a posttransplant setting has emerged as a difficult problem in kidney transplantation (KT). Lymphoma involving adnexa of the eye has rarely been reported due to scarcity of lymphoreticular tissue in the ocular area. This report presents a case of a 37-year-old KT recipient who was diagnosed with conjunctival mucosa-associated lymphoid tissue lymphoma with a chief complaint of seeing black spots. Unlike other post-transplant lymphoproliferative diseases associated with the Epstein-Barr virus (EBV) reactivation via immunosuppression, the lesion was not related to the virus. The patient received radiotherapy with concomitant conversion from the tacrolimus to the sirolimus. Overall, the results presented herein indicate lymphoma may be an important differential diagnosis when KT recipients complain of ocular discomfort.
