Kidney Preserving Surgery in Renal Trauma:. Experience by Early Vascular Approach Technique / 대한비뇨기과학회지

PURPOSE: To evaluate the usefulness and safety of unified technique of vascular control before renal exposure in reconstructive surgery of renal trauma. MATERIALS AND METHODS: From July 1995 to June 1997, 10 patients with major renal trauma who operated by unified approach technique were included in this study. Blunt trauma was the mechanism of injury in 8 patients and 2 were resulted from penetrating(stab) injury. Of the injuries 2 were grade 3, 7 grade 4, 1 grade 5. RESULTS: Of the 10 patients, 8(80%) were performed kidney preserving surgery and 2(20%) resulted in nephrectomy. Partial nephrectomy was underwent in 6 patients(with vascular repair in 2 cases) and renorrhaphy in 2 patients. Pedicle flap of omentum was used mainly and polyglycolic acid mesh also used in 2 cases as coverage material of parenchymal defect. Complications occurred in 2 cases(20%) but none resulted in renal loss with the mean followup of 10 months(1 to 15 months). CONCLUSIONS: Unified approach technique of vascular control before renal exposure seems to be a safe and effective method for reconstructive surgery in renal trauma. To confirm this result, studies with more cases and longer followup are needed.

Renal Injury in Abdominal Trauma: Assessment of Incidence and Risk in the Admitted Patients / 대한비뇨기과학회지

PURPOSE: To estimate the incidence and risk of significant renal injury quantitatively in the admitted patients with abdominal trauma. MATERIALS AND METHODS: From January 1992 to July 1997, 511 patients who admitted to departments of urology and general surgery due to major abdominal trauma with and without renal injury were included in this study. The risk of renal injury was defined as the percentage of square of Abbreviated Injury Scale of kidney in the Injury Severity Score(ISS) per each patient. The patients were classified to 5 groups according to the causes of trauma as traffic accident, falls, assault, other blunt and stab Injury, then compared the incidence and risk of renal injury each other. RESULTS: The overall incidence of significant renal injury was 14.9%, and the incidence according to the causes was 27.0%,20.8%, 16.1%, 14.3% and 10.7% in falls, assault, stab injury, other blunt and traffic accident, respectively. The overall risk of significant renal injury estimated by ISS was 15.7% and the risk according to the causes was 26.7%,24.9%, 11.9%,9.9% and 4.9% in assault, falls, traffic accident, other blunt and stab injury, respectively Mean ISS in the patients with renal injury was markedly higher than that of the patients without renal injury(27.5 vs 13.6)(p < 0.01). CONCLUSIONS: Our study shows that both the incidence and risk of significant renal injury in the admitted patients with abdominal trauma can be expected in the probability of 15% or so, and according to the causes, those in the traumatized patients by the assault and falls mark high.

A Case of Extensive Emphysematous Infection in Renal Cell Carcinoma / 대한비뇨기과학회지

Emphysematous urinary tract infection is a rare, life-threatening necrotizing infection characterized by gas generation, and usually occurs in patients with diabetes and/or urinary tract obstruction. We herein report a unique case of emphysematous renal infection occurred in. an old diabetic man with renal cell carcinoma. This case suggests that renal cell carcinoma should be also considered a rare cause of emphysematous renal infection showing mass contour.

Clinical Observation on the Cryptorchidism / 대한비뇨기과학회지

A clinical observation was made on 116 patients of cryptorchidism who had been admitted to the Department of Urology, Gil Genersl Hospital during 34 months from March, 1992 to January l995. The results were as follows: 1. The age distribution varies from to 1 to 33 years and the most frequent group was l to5 years old(62%). 2. Bilateral cryptorchidism was found in 22 cases(19%), and in the case of unilatera1, right in 52 cases(44.8%) and left in 42 cases(36.2%). 3. Of the 138 testes, most frequent location was in the inguinal canal in 123 testes(89.1%). 4. Orchiopexy was perrormed on 130 testes(94.2%) by subdartos pouch technique and 7 testes were performed the orchiectomy 5. Among the associated anomalies, the most common anomaly was inguinal hemia in 131 cases and others were contralateral hydrocele, hypospadias, congenital heart disese and syndactyly.
