A trying to evaluate acute renal tubular damage after ESWL / 대한비뇨기과학회지

Determination of urinary marker proteins was carried out trying to evaluate renal tubular damage as a part of renal injury caused by ESWL via EDAP LT-01+lithotiptor. All of twenty patients undergoing ESWL, suffered from unilateral, nonobstructive, infection-free, and previously untreated renal stone (s). Two urinary marker proteins, N-acetyl-beta-gluoosaminidase (NAG) and beta 2-micmglobulin (beta2-M) were monitored in all the patients 1 day before, 1 and 3 day (s) after ESWL using total 100 storage of 3 sessions which is average therapeutical dose. Urinary level or NAG (normal value; 0.29-7.23 U/L) was 1.66+/-1.31 1 day before, 1.97+/-1.57, 2.66+/-2.90 U/L 1 and 3 day (s) after ESWL respectively. beta2-M level (normal value <300 ug/L) was 142+/-137 1 day before. 133+/-100, 151+/-186 ug/L 1 and 3 day(s) alter ESWL, respectively. Consequently it was concluded that ESWL using average therapeutical dose (100 storage) via EDAP LT-01+ litholriptor can hardly develop renal tubular damage.

Initial Experience of Percutaneous Removal of Upper Ureteral Stone / 대한비뇨기과학회지

We tried percutaneous extraction of upper ureteral stones in five patients via Wolf rigid ureteroscope with grasping forceps. The procedure was performed at two session. The nephrostomy tract dilation was carried out by combination of metal dilator and Amplatz teflon renal dilator under fluoroscopy. All the five cases of PCN were successful without any complication at first trial. The advantage of this technique is low postoperative morbidity, rapid convalescence, sooner return to work and cheap price. It seems that endourological treatment of mid ureteral stone as well and upper ureteral stone can be extracted through percutaneous nephrostomy tract.

A Study for Clarifying the Necessity of Additional Antibiotic Therapy in Patients Undergoing TURP, Given Antibiotics During Catheter-indwelling and Showing Sterile Urine after Catheter-removal / 대한비뇨기과학회지

Faced with patients who underwent TURP and who were given antibiotics until catheter-removal, usually complain of urinary frequency or burning on ruination and showing sterile urine (less than l00 bacteria per ml., in clean-caught midstream about 24 hours after catheter-removal), we often hesitate to make a decision whether they should be given antibiotics or not. So we divided 27 such patients into three groups : group l ; 7 patients, no additional antibiotics after catheter-removal, group 2; 12 patients, antibiotics for one week after catheter-removal and we performed weekly urine culture for clarifying the necessity of additional antibiotic therapy and its appropriate duration, if necessary. The following results and conclusions were obtained. I. Group l showed bacteriuria in 86%(6 of 7 patients). 2.Group 2 and 3 showed bacteriuria 5%(1 of 20 patients). 3. These data suggested that additional antibiotic therapy rather than stopping antibiotic therapy might be justified(P : less than 0.001). 4. Group 2 showed no bacteriuria and group 3 showed bacteriuria in one patient which disappeared promptly. Namely, there was no practical difference in the incidence of bacteriuria between the two groups. 5. 9 cases of fungiuria were found, all of which developed in patients given antibiotics perioperatively for more than 2 weeks. 6. Considering the above items and cost-effectiveness, a week`s additional antibiotic therapy is probably an appropriate answer to treating the above-mentioned patients. 7. Main causative organism in post-TURP bacteriuria was Pseudomonas spp(4of 7 cases).

A Case of Retroperitoneal Tuberculoma / 대한비뇨기과학회지

Tuberculoma means a tumor-like mass resulting from enlargement of a caseous tubercle which microscopically shows infiltration of epithelioid cells, Langhans giant cells and lymphocytes. In a 57-year-old woman suffering from left renal tuberculosis, we incidentally found a large retroperitoneal tuberculoma (site: retrohepatic, above right adrenal gland, below diaphragm and outside Gerota`s fascia, size: 13X11x9cm). Generally, Mycobacteria tuberculosis invade the lung via airway, and subsequently, they can be disseminated to any organ or tissue. They are apt to establish disease in the organ or tissue of high oxygen tension level. We report a case of retroperitoneal tuberculoma with wonder that it could develop in the retroperitoneum of poor blood supply.

Congenital Anterior Urethral Diverticulum: A Report of Two Cases / 대한비뇨기과학회지

Urethral diverticula in children occur primarily in males. Although the etiology can be secondary to distal meatal stenosis with infection, most of them are congenital in origin. Being easily overlooked, anterior urethral diverticula are not uncommon and should always be borne in mind in cases of bladder outflow obstruction. With brief review of literatures, we report 2 cases of congenital anterior urethral diverticulum found in a 4-year-old boy and a male newborn.
