2.Anatrophic nephrolithotomy: experience in 55 cases.
Yeungnam University Journal of Medicine 1992;9(1):149-155
55 consecutive anatrophic nephrolithotomies on 53 patients performed between July, 1983 and June, 1990 were reviewed. The patients (36 male and 19 female) ranged in age from 3 to 72 years. The operation time averaged 219.8 minutes with a range of 120-330 minutes, and the ischemic time ranged between 20 and 90 minutes, with a mean of 43.5 minutes. Postoperative complications developed in 18 patients, which were such as persistent urinary tract infection in 5cases (9.4%), atelectasis in 4 (7.5%), transient urine leak in 2 (3.8%), delayed bleeding in 2 (3.8%) and urinary retention in 2 (3.8%). Postoperative residual stones were identified in 15 (27.3%), but in 8 of these 15patients stones were delivered spontaneously and thus 48 of 55 cases (87.3%) became stone free. The recurrence of stone was noted in 2 out of 48 patients during the short follow up period. Anatrophic nephrolithotomy seems to be an effective method compared to other procedure because of decreasing recurrence of stone by complete stone removal and reconstruction of abnormal collecting system.

4.Factors influencing the success rate of pregnancy following microscopic vasovasostomy for postvasectomy sterility.
Seong Jong MO ; Tong Choon PARK
Korean Journal of Urology 1991;32(3):444-451
Vasectomy has become a popular method for male sterilization in Korea and this, in turn, has been followed by an increase in the number of patients requesting vasectomy reversal. Recently, many authors have reported a high success rate of vasovasostomy using microsurgical techniques. However, a significant discrepancy persist between the patency and pregnancy rate despite improvements in surgical techniques. A total of 200 patients undergoing vasovasostomy from May 1983 to April 1990 were reviewed. Of these 200 patients, only 130 patients (98 patients by two-layer, 32 patients by modified two-layer technique) could be followed up and analyzed as to pregnancy rate related to age, vasal obstructive interval, gross appearance and sperm quality of the vas fluid, operative method, and presence or absence of sperm granuloma. Success rates were 90.3% for patency and 65.4% for pregnancy. With regard to factors influencing to operation, it seemed that the results were better when there was a shorter vasal obstructive interval, watery vas fluid, presence of normal morphologic sperm quality, presence of sperm granuloma, and when the operation was done using the two-layer technique. However, no statistically significant difference was found, except between the bilateral presence and absence of sperm granuloma at the vasectomy site. Thus it is suggested that the most important single factor influencing the success rate of vasovasostomy is a meticulous and skillful operative technique itself, althought other factors may affect the outcome. More effort and research are needed to find the factors affecting the success rate of vasovasostomy.

5.2 cases of male urethral diverticulum combined with stone.

Male urethral diverticulum is uncommon lesion, furthermore calculus formation within the male urethral diverticulum is very rare. Generally, urethral diverticula are classified as congenital and acquired. The majority of male urethral diverticula are acquired and approximately 10 to 20 per cent are congenital. Acquired urethral diverticula in the male may arise from many sources, including infection (prostatic abscess, infection of periurethral glands, hematoma or schistosomiasis), obstruction (stricture, impacted stone, Cunningham clamp or condom catheter) and trauma (instrumentation, external injury and pelvic fracture). Calculi formation is more common in the acquired diverticulum owing to stagnation of urine and infection. These calculi in the diverticulum usually are solitary and may attain considerable size with predisposing factors, 1) a ureteral or bladder calculus that is lodged in the urethra 2) urethral trauma or stricture, 3) calcification around a foreign body or hair. The treatment of urethral diverticulum combined with stone is excision of the diverticula with removal of stone. We treated two cases of urethral diverticulum combined with stone in the male, and report with review of literature.

Management of the small lower ureteral stone has been attempted by either transurethral manipulation or expectant therapy. To date, however, the choice of proper method has depended mostly on clinician's preference, and the effectiveness of the transurethral stone manipulation has remained controversial. Herein we evaluated the effectiveness of the transurethral stone manipulation, using with the Dormia dislodger, in 37 patients with lower ureteral stone less than 10mm in greatest diameter. The results are summarized as follows. 1. The overall success rate was 68% (25 of 37 patients); Immediate delivery of the stone was observed in 16 of 37 patients. In another 5 patients the stone was removed at the time when the indwelled ureteral catheter was taken out. In the remaining 4 patients the stone passed spontaneously within a week following the procedure. 2. Higher success rate was observed in smaller stone; 79% in less than 4 mm, 58% in 46 mm, and 33% in 610 mm in it's greatest diameter, respectively. 3. The morbidity rate was 8.1% (3 of 37 patients); In one patient a broken basket was retained in the ureter, which was removed at the time of ureterolithotomy. In another patient a ureteral stricture requiring periodic dilation was complicated. And in the other patient persistent hematuria was observed, which was relieved by conservative management. These results suggest that transurethral manipulation might have to be initially applied to unremittingly painful patients with small lower ureteral stone.

Ureteroscopic removal of the stone is now popular for the management of the lower ureteral stone. A clinical study was performed on our 75 patients with lower ureteral stone treated with ureteroscopy. Of the 75 stone manipulations 62 (83%) were immediately successful and the final success rate including spontaneous delivery of stone or fragment after the procedure was 87 percents (65 cases). Of 57 smaller calculi than 1 cm (radiographic largest diameter) 50 (88%) were removed successfully. Mean duration of postoperative hospitalization was 5.6 days. There were no interrelations between the success rate and anesthetic methods. Significant complications during or after procedure were not identified. We conclude that ureteroscopic removal of stones under direct vision can be done safely and be the first choice of procedure for the lower ureteral stones.

10.Effect of Ethanol Injected into Tunical Cavity on Scrotal Wall and Testicle in Rats.
Korean Journal of Urology 1989;30(5):649-654
Noncommunicating hydrocele in adult is the most frequently encountered mass of the scrotum. Traditionally surgery had been considered as the most effective method of treatment. Sclerotherapy, however, may provide an alternative means of treatment for patients who are poor surgical or anesthetic risks and those who refuse surgery. In recent years, a number of sclerosing agents including tetracycline have been introduced, but those were found to produce various kinds of complications or frequent recurrences. Alcohol was also proved to have sclerosing effect by Bean who used it in the treatment of simple renal cysts with good results. This study was designed to determine the feasibility of sclerotherapy with alcohol for noncommunicating hydroceles. 95% or 75% sterile alcohol and tetracycline were injected into the spaces of tunica vaginalis of male rats to produce fibrous adhesion. At second week after injection, There was no significant difference in successful adhesion rates between alcohol injection group (71.9%) and tetracycline injection group(75%). 95% alcohol seemed more effective than 75% alcohol. There was no specific change or damage in the testicular parenchyme or surrounding scrotal wall. This result suggests the clinical applicability of alcohol in the management of noncommunicatinghydroceles.
