A clinical observation was made on 112 cases of hypospadias which were treated at the Department of Urology, Seoul National University Hospital during the period June 1977 through May 1982. The results were as follows: 1. The ages were distributed from 7 months to 31 years and most of the cases (64.3%) was treated in the age group of less than 7 years. 2. Most of the types of hypospadias was penoscrotal type (43.8%). 3. Cryptorchism was the most frequent associated anomalies with 21 cases (18.8%). 4. The complication rate of other anomalies was greatest in the perineal type (81.8%). 5. Success rate of one-stage urethroplasty was 52.9%. 6. In two-stage operation, the first stage operation of 97 cases was successful except one of incomplete chordee release and the success rate of Thiersch-Duplay and Johanson second stage urethroplasty was 44.4% and 66.7% respectively. 7.

A 14-year old girl presented with urinary incontinence along with normally secured voluntary voiding. Careful physical examination revealed leakage of urine through a small opening near the vestibule, ventral to the urethral meatus. Cystoscopically, the right ureteral orifice was absent but otherwise normal. Nonfunctioning right kidney was found on excretory urography. A #4 ureteral catheter was inserted into the ectopic opening as high as 10cm, and the retrograde pyelogram showed dilated right ureter ending blindly at the level of lumber vertebra II with stricture at the level of the tip of the catheter. After the right nephroureterectomy, she became dry and was discharged on the 12th postoperative day. The removed kidney weighed only 8 Gm. and pathological diagnosis was congenital hypoplasia of the right kidney with ectopic ureteral opening.

One hundred and twenty male rabbits were divided into 8 groups in order to studythe effect of castration and sex hormone administration on water and electrolytesdistribution in kidney, small intestine and lung tissue as follows:Group 1: control (non castrated)Group 2: estrogen injectedGroup 3: androgen injectedGroup 4: progesterone injectedGroup 5: castration control (castrated)Group 6: estrogen injected and castrationGroup 7: androgen injected and castrationGroup 8: progesterone injected and castrationFourteen days after castration, each rabbit in groups 6, 7 and 8 was administeredwith 2,000 units of estrogen, 400 units of androgen and 400 units of progesteronddaily for 3 days consecutively. Three days after the final injection, they weresacrificed by means of cardiac puncture. Immediately after sacrificing the animals, kidney, lung and small intestine were removed to determine the contentsof tissue water. Na, K and Cl. Water content was determined by drying method in 1O0 degrees C oven until the weight remained constant. Na and K in serum and tissue wereanalyzed with Baird flame photometer using lithium nitrate as internal standard.Serum Cl was analyzed by the method of Schales and Schales and tissue Cl by theVan Slyke's. The conclusion is as follows: 1) In control rabbits (non castrated), serum concentration of Na and K was decreased while Cl concentration was increased after administration of estrogen, androgen and progesterone. 2) In castrated rabbits, serum concentration of Na was increased, while K was decreased. Na and K were decreased, while Cl was increased by the administration of sex hormone after castration. 3) In kidney tissue of non castrated rabbits, water content was slightly increased by the administration of sex hormone. The changes in concentration of Na, K, Cl. extracellular space and total Na + K were not significant, while K was increased remarkably in the progesterone group. Also the total Na + K [cell water (Na)] was remarkably increased as high as 47%. 4) In kidney tissue of castrated rabbits, water content and Na were increased, whereas K and Cl were decreased. The administration of sexhormone acted inclusively on the restoration of these levels to the precastration state. The androgen injection provided the most effective result. 5) In lung tissue of non castrated rabbits, Na and K were decreased by the administration of sex hormone. In the androgen group, a decrease of Na and K was most remarkable, Cl in the progesterone group, and Na space and total Na+K in the androgen group were decreased remarkably. 6) In lung tissue of castrated rabbits, water content was increased, and Na, K and Cl were all decreased. The administration of sex hormone acted inclusively on the restoration of these levels to the precastration state. In general, the androgen was most effective among hormones given. 7) In small intestine tissue of non castrated rabbits, Na, K and Cl were increased and also the extracellular space and total Na+K were inclusively increased. 8) In small intestine tissue of castrated rabbits, water content and K were increased while Na was decreased. The administration of sex hormone acted on the restoration to the precastration state in the water content and Na. The androgen was most effective among hormones given.
