It has been known that immobilization of patient caused by chronic illness, orthopedic or neurological conditions can be one of etiological factorof urinary stone The authors have recently experienced a case of renal sand filling the pelviwalycea1 system simulating renal staghorn calculus which wasspontaneously flushed out following excessive fluid intake and forced mobilization. This patient had stones in the contralateral kidney and ureter.

Primary vesicoureteral reflux, distal ureteral obstruction or stricture and injuries are the main indications for the ureteroneocystostomy There are several operative techniques in ureteroneocystostomy and these should be antireflux to preserve renal function. To prevent the reflux, sufficient submucosal length, minimum ureteral manipulation, adequate butters and making the new orifice near the trigone are stressed. We performed ureteroneocystostomy in 19 patients(20 ureters) in last 10 years. We evaluate the preoperative state, operative technique, postoperative course and follow up of these cases and report with the review of the articles Results were 1. 19 cases included 5 VUR, 6 ureteral injuries by transabdominal hysterectomy, 3 bladder tumors involving ureteral orifices, 2 ureteroceles with obstruction and 3 chronic inflammatory strictures. 2. Ureteroneocystostomy were done by Cohen in 4, Glenn-Anderson in 2, Politano-Leadbetter in 3, Boari-Kuss in 5, Paquin in 2 and fish-mouth in 3 cases 3. Ureteral stent and suprapubic cystostomy were made in all cases but one. Duration of stenting was 4-14 days and cystostomy was 6-14 days. 4. There were improvements in 16 cases, but failed in 2 ureters of reflux cases.

Among causes of acute scrotum, epididymitis and testicular torsion are most common causes. There is difficulty in differential diagnosis of testicular torsion and acute epididymitis because of their similarities in clinical features. Recently, the radioisotope testicular scanning in imaging procedures has been introduced as that is simple, rapid and a high accuracy. So, 28 cases with scrotal swelling and pain were studied by means of testicular scanning in the Department of Urology, Kyung Hee University Hospital during the period from February, 1981 to September, 1983. The following results were obtained: 1. 2 cases those were diagnosed as testicular torsion clinically showed typical findings of torsion on scanning. They were confirmed as torsion by operation. 2. 16 cases were diagnosed as acute epididymitis clinically. 13 of them gave the scan findings compatible with epididymitis and all cases were well improved with antibiotic therapy. Remaining 3 cases showed findings of torsion and were confirmed surgically. 3. 8 cases were diagnosed as testicular injury clinically. In 5 cases scan showed findings of trauma and were also confirmed by operation. In the other 3 cases. scan showed findings of epididymitis and all of them were improved with antibiotic therapy. As above results testicular scan is easily available and accurate diagnostic method in the evaluation of patient with acute scrotal disorders.

Undescended testis is one of the most common anomalies of genitourinary tract in children but optimal time for treatment of it has not been determined still. We examined the changes of seminiferous tubules according to ages in 41 patients with undescended testis which orchiectomy or testicular biopsy were performed in the Department of Urology, Kyung Hee University Hospital during the period from January, 1979 to April, 1985 and following results were obtained. l. The ages of 41 patients ranged from 6 years to 48 years. Of these,36 patients were unilateral and 5 patients were bilateral undescended testis. 41 undescended testes were located in inguinal canal, 2 in high scrotum and 3 above the internal inguinal ring. 2. Mean Tubular Diameter was average 48.5 Um from 6 years to 12 years, 81.2 Um at 14 years and 118.4 Um at 24 years. But in normal group, it was average 95.7 Um from 6 years to 12 years, 2l3.6 Um at 14 years and 229.4 Um at 17 years. So, there was already severe damage in development of seminiferous tubules in undescended testis at 6 years. 3. Mean Tubular Fertility Index was average 19.7% from 6 years to 17 years, 42% at 19 years, average 10.8% from 20years to 30 years and 0% at 48 years. But in normal group, it was 78.0% at 6 years and 100% at I4 years. So. there was already severe damage in formation of spermatogonia in undescended testis at 6 years. 4. The thickness of basement membrane of seminiferous tubules in undescended testis was 2.2 Um at 6 years and increased with age to 9.9 Um at 24 years.

Urodynamic studies including uroflowmetry, CO2 cystometry, electromyography, urethral pressure profilometry were performed on 15 cases of the chronic prostatitis in the Department of Urology, Kyung Hee University Hospital recently. The following results were obtained: 1. The uroflowmetry was performed in 15 cases. The average of the maximum flow rates was 16.57+/-4.68ml/ sec (M+/-SD). In only 4 cases the maximum flow rate was within normal range, but the other 11 cases revealed decreased rates than normal. 2. The CO2 cystometry was performed in 14 cases. In only one case the bladder capacity was 1,003ml, but the other findings were normal. The other 13 cases revealed normal findings. In 12 cases the external anal sphincter EMG was performed with cystometry simultaneously, there was no detrusor-sphincter dyssynergia. 3. The urethral pressure profilometry was performed in 14 cases. The average of the functional profile length was 3.06+/-0.78cm (M+/-SD). The average of the maximum urethral pressure was 85.36+/-27.99cmH

Authors reviewed 110 cases of retrograde pyelography which performed in the Dept. of Urology, Kyung Hee University Hospital during the period from January 1977 to December 1980. And the results were as follows. 1. Indication was 34 cases (31%) of nonvisualizing kidney, 31 cases (28%) of obstructive lesion, 21 cases (19%), of inadequate filling in pelviocalyceal system, 7 cases (6.5%) of impaired renal function. 6 cases (5.5%) of upper tract abnormality, l cases (0.9%) of allergy to contrast media and other 10 cases. 2. On the nonvisualizing kidney, hydronephrosis (23.5%) was most common and normal (20.5%), ureter stone (20.5%) in order. 3. For assessment of obstructive lesion, UPJ stricture (39%) was most common and ureter stone (32%), normal (16%), ureter tumor, UVJ stricture in order. 4. Inadequate filling on excretory urogram revealed normal (24%), renal tumor (19%), renal tuberculosis (9.5%) and chronic pyelonephritis scar (9.5%) etc. 5. The patients who had poor renal function or poor general condition and upper tract abnormality were well defined with retrograde pyelography and available for diagnosis and treatment. 6. Complication were seen in 2 cases (1.8%). One was acute pyelonephritis and the other was pyonephrosis.

A retrospective analysis of 132 patients who underwent nephrectomy in the Department of Urology, Kyung Hee University Hospital, during the period from January 1972 to December 1980 was presented. The results were as follows: 1. The total number of in-patients during the above period was 2,301 and nephrectomies were performed in 132 of 1,427 total urologic operations (9.3%). 2. Age distribution showed the highest in 4th decade with 22.7%, the youngest was 11 months and the oldest 78 years, and male to female ratio was 68 to 64. 3. The causative diseases of the nephrectomy were renal tuberculosis 48 cases (36.4%), tumor 15 cases 11.4%. hydronephrosis 11 cases (8.3%), pyonephrosis 10 cases (7.6%), anomaly 8 cases (6.1%) and hypertension 6 cases (4.5%) in order. 4. Anterior abdominal extraperitoneal transverse approach was the most frequently used method in 103 cases (78.0%) 5. Post-operative complications were seen in 29 cases (22.0%), of which wound infection was common in anterior abdominal extraperitoneal transverse approach.
