Epidermoid Cyst of Testis / 대한비뇨기과학회지

A 24-year-old man visited our hospital with painless scrotal mass 2 weeks in duration. Physical examination revealed about 3cm in diameter, ovoid, hard, movable and painless mass in the left side of the scrotum. He had no history of trauma, voiding difficulty or infection sign. CBC, blood chemistry and tumor marker were normal. Left orchiectomy was done. Tumor was a well encapsulated white-gray ovoid mass filled with yellowish gray material and histogically diagnosed as epidermoid cyst. Benign tumors of testis are rare, acounting for less than 1% of all testicular tumors. Herein we report a case of epidermoid cyst of testis and review the literatures.

Computed Tomographic Appearance of Orthotopic Neobladder: Correlation with Voiding Pattern / 대한비뇨기과학회지

PURPOSE: To define computed tomographic (CT) appearance according to voiding patterns and to evaluate the significance of CT in patients with voiding dysfunction after orthotopic bladder substitution following radical cystectomy. MATERIALS AND METHODS: We evaluated a total of 50 male patients in whom 25 had undergone an ileocolic and 25 had undergone an ileal neobladder. We performed uroflowmetry, postoperative voiding cystourethrography (VCUG) and CT for evaluation of configuration of neobladder according to voiding pattern. We defined a good voider (n=37) as the patients with maximum flow rate greater than 15 ml/sec and postvoid residual urine amount less than 200ml and a poor voider (n=13) as those with less than 15 ml/sec or greater than 200ml. RESULTS: Voiding cystourethrography revealed that the neobladder outlet was well funneled and wide open at the most dependent portion of the neobladder in good voider group. However, in poor voider group, the neobladder outlet was not funneled or deviated from its caudal location. CT revealed that the neobladder was symmetric in 28 cases (75.7%) and had soft tissue density in the neobladder base in 9 cases (24.3%) of good voider group. However, neobladder was asymmetric in 8 cases (61.5%) and had soft tissue density in the neobladder base in 8 cases (61.5%) of poor voider group. CONCLUSIONS: The asymmetry of neobladder and soft tissue density around base of neobladder on CT may be associated with the deviated neobladder outlet. This CT finding might be useful to presume the cause of voiding pattern.

Hand-Assisted Laparoscopic Live Donor Nephrectomy / 대한비뇨기과학회지

PURPOSE: Hand-assisted laparoscopic live donor nephrectomy (HALDN) are being performed at our institution in an attempt to make live donor more attractive to the potential donor. We review the results of HALD N retrospectively and compare them with those obtained using the standard open approach. MATERIALS AND METHODS: 9 consecutive HALDN were performed from February 2000 through June 2000. The control group consisted of the 22 open donor nephrectomy at the same institution from January 1999 through December 1999 immediately before the initiation of HALDN. Live donors were considered candidates for HALDN if they possessed left normal renal anatomy with single renal vessels and ureter. Among 9 HALDN patients, one patient had two main renal arteries and another one patient had a polar artery. We evaluated sex, age, body weight, BMI (Body Mass Index) basically. And we evaluated renal ischemic time, operation time, to normal activities, postoperative serum creatinine level, and postoperative complications. RESULTS: There was no significant difference in male-female ratio, age distribution and weight-height ratio between two groups. Warm ischemic time for HALDN group was 3 to 4 min and it was not different with open surgery. Operation time was prolonged in HALDN group (284.4+/-72.8 min) compared to open group (193.1+/-26.7 min) (p
