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.

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.

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.

Medullary sponge kidney is a relatively common, congenital lesion of the renal medulla, which was first described by Lenarduzzi in 1939. Many urologists have been interested in its unknown pathogenesis and complications, such as nephrolithiasis and infection. We report 5 cases of medullary sponge kidney, diagnosed by excretory urography and the literature has been reviewed briefly.

Daily excretions of sodium, potassium and urea nitrogen and urine volume of normal Korean were reported by several authors. However, it is generally suspected that dietary composition of Koreans improved during last decade. Author have hypothetized that changes of diet composition could modify urine compositions and volume. In order to determine the urine composition and volume in the late 1970`s, sodium and potassium concentrations were measured by flame photometry and urea nitrogen by urease indophenol method in the urine from 50 rural residents. The residents were composed of 10 public officials, 18 male farmers and 22 female farmers. Followings were the results: 1. Daily urine volume Total average : 1594.20+/-443.89 ml/day, Public official : 1714.00+/-548.00 ml/day Male farmer :1508.89+/-310. 54ml/day, Female farmer: 1612.27+/-496.04 ml/day 2. Daily urinary sodium excretion Total average : 5.19+/-1.21 g/day. Public official : 5.62+/-1.93 g/day Male farmer : 4.73+/-1.10 g/day, Female farmer: 5.37+/-0.98 g/day 3. Daily urinary potassium excretion Total average : 1.79+/-0.59 g/day, Public official : 1.97+/-0.60 g/day Male farmer : 1.91+/-0.59 g/day, Female farmer : 1.62+/-0.58 g/day 4. Daily urinary urea nitrogen excretion Total average : 7.26+/-l.95 g/day, Public official : 8.06+/-1.65 g/day Male farmer: 7.53+/-2.40 g/day. Female farmer : 6.67+/-1.65 g/day A comparison of these data with corresponding figures obtained from Western reporters indicate that the concentration and excretion of sodium of rural Koreans are still higher significantly, while those of potassium and urea nitrogen are lower than those of Westerns significantly. On the other hand, a comparison with corresponding figures obtained from other Korean reporters in the 1960's indicate that sodium excretion of present data is lower while potassium and urea nitrogen are higher than those of the 1960's. It is speculated that these peculiarities of urinary composition shown in rural Koreans in the late 1970's are attributed to improved protein ingestion combined with decreased salt intake as compared to 1960's, however, the levels are still far from Westerns.
