A Case of Embryonal Rhabdomyosarcoma of the Bladder / 대한비뇨기과학회지

A case of embryonal rhabdomyosarcoma of the bladder in a 6-month-old male infant, who presented dysuria with straining and dribbling, and a suprapubic palpable hard mass distinct from the distended bladder, was reported with brief review of literatures.

A Clinical Observations on Bladder Rupture / 대한비뇨기과학회지

A clinical observation was made on patients of bladder rupture who were admitted to the Department of Urology, Chonnam University Medical School during the period from January, 1978 to June, 1982. The results are as followings: 1. Of 128 cases of genitourinary injury, there were bladder rupture in 32 cases, giving a rate of 24.2%. 2. The age group from third to fifth decade was the most favorable in age incidence, showing 59.4% of the total patients. 3. Traffic accident was the most frequent cause of the injury, observed in 9 cases (28.1% of all patients). Alcohol drinking was suggested to be related to the injury in 7 cases (21.9% of all patients). 4. Occurrence of intraperitoneal ruptures was three times more then that of extraperitoneal ruptures. 5. Retrograde cystography was the most useful and reliable method for diagnosis of bladder rupture, but there were falsely negative cystograms in two cases. 6. There were two cases with simultaneous bladder rupture and disruption of the posterior urethra, in which cases making diagnosis as bladder rupture was difficult without exploration. 7. Immediate vesical repair and indwelling urethral catheter, with or without suprapubic cystostomy, were performed in almost all patients, except two cases who were only managed with indwelling urethral catheter. 8. While we had four cases of intraperitoneal rupture with complication we couldn't find any complications in cases of extraperitoneal rupture.

Analysis of Urinary Calculi / 대한비뇨기과학회지

One hundred thirty-seven urinary calculi were analyzed by means of X-ray, diffraction, ultraviolet spectroscopy and chemical method. 1. The most frequently found constituent in these 137 calculi was calcium oxalate that was found in 101 calculi (76.0% of the series). Of these 104 calculi pure calcium oxalate was identified in 41, of which 14 (10.2%) were composed of pure monohydrate and 27(19.7%) were mixtures of monohydrate and dihydrate. The dihydrates were only found to be mixed with monohydrates and the two hydrates could be identified only by X-ray diffraction but not by chemical method. 2. Identification of phosphate by X-ray diffraction was difficult because of its low peak intensity, while chemical method was proved to be more sensitive and accurate for phosphate. Calcium phosphate was found not in the pure state but in the: mixed form with calcium oxalate in 39 calculi (28.5%). 3. Pure uric acid constituent was very rare, being oily found in 2 calculi (1.5%). But there were 41 calculi (29.9%) mixed with a minute amount of uric acid, of which 28 (68.3%) were associated with calcium oxalate monohydrate. Only one calculus of uric acid, which did not appear to be crystallized, was detected by ultraviolet spectroscopy. 4. There were 23 calculi (16.8%) of magnesium ammonium phosphate, of which 13 (56.5%) were mixed with calcium phosphate and only 3 (13. 0%) were found to be in the pure state. 5. Xanthine was found as a minor constituent in t calculi, all coexistent with uric acid. There was no calculus of cystine detected. 6. X-ray diffraction method bad the advantages of providing a permanent record and a semiquantitative result and of identifying minute components. However it was unsatisfactory for detecting phosphate constituent.
