A Study of the Effect on Sperm Motility by Mycoplasma / 대한비뇨기과학회지

This study was carried out to investigate the effect of Mycoplasma on sperm motility. It was suspected that a GUT infection due to Mycoplasma could be a possible cause of infertility. Human fresh spermatozoa from 57 healthy medical students were mixed and diluted with Mycoplasma groups. 37 specimens to T-mycoplasmas and 20 specimens to M. hominis were exposed with varying concentration from 10,000 to 1,000,000 colonies/ml of broth, respectively. Spermatozoal motility scale devised by Emmens and pH by pH paper were checked at serial time of hours in vitro. The following results were obtained. 1. There is no significant effect on sperm motility in pH change by Mycoplasma. 2. The sperm motility of control groups among pure semen, semen with normal saline and semen with broth solution were no statistically significant differences (p>0.05). 3. The statistically significant decreased sperm motility was watched in T-mycoplasmas experimental groups than that of control groups. The motility was much decreased with higher concentration of organisms (p<0.05). 4. The statistically significant decreased sperm motility was also watched in M. hominis experimental groups than that of control groups (p<0.05) The motility was much decreased with higher concentration of organisms.

A Clinical Observation on 30 Cases of Urologic Surgery Using the Intestinal Segments / 대한비뇨기과학회지

A clinical observation was made on 30 patients of urologic surgery using the intestinal segment who had been admitted to the Department of Urology, Chungnam National University Hospital from May, 1976 to April, 1982. The results are as follows; 1. The age distribution of the most of cases were fifth and sixth decades (66.7%), and the male to female ratio was 3.3 to 1. 2. Majority of underlying diseases was bladder tumor (76.6%). The other causes were neurogenic bladder (10.0%), Vesicovaginal fistula (10.0%) and contracted bladder (3.3%). 3. Of the 30 cases of urinary diversion, 24 cases were ureteroileocutaneostomy with or without total cystectomy, 3 cases were ureterocolocutaneostomy with total cystectomy, 2 cases were ureteroileocecocutaneostomy with total cystectomy and 1 case was augmented ileocecocystoplasty. 4. Operation mortality was 10%, in which underlying diseases were bladder cancer. 5. Major complications were acute renal failure, septicemia, wound disruption, urine leakage, fecal fistula, ileus, bleeding, pneumonia and evisceration. 6. In the 23 cases of bladder cancer 21 cases were transitional cell carcinoma and 2 cases were adenocarcinoma. Most of the former were composed of stage B & C (66.7%) and grade II & III (71.4%). 7. In cases of malignant disease the overall postoperative survival rate at 1, 3 and 5 years of bladder cancer were 73.9%, 50% and 20% respectively.

A Case of Ileocecocystoplasty / 대한비뇨기과학회지

Ilecocecal unit is anatomically and functionally well suited for augmentation cystoplasty. There is no need to artificially create a cap or tailed path because the cecum can be used without such alteration. Herein, we describe as experience with a 14 years old male patient whose bladder capacity was less then 90 ml due to renal tuberculosis. Previously, patient received right nephrectomy and temporary cystostomy to prevent vesicoureteral reflux. Augmentation ileocecocystoplasty was performed Department of Urology in this hospital on patient with good results : considerable enlargement of bladder capacity without vesicoureteral reflux.

A Case of Primary Urethral Adenocarcinoma in Female / 대한비뇨기과학회지

Primary carcinoma of the female urethra is an uncommon neoplasm that accounts for less than 0.02% of all malignant diseases occurring in women. Especially reported adenocarcinoma is rare now in the literature. We add one case of urethral adenocarcinoma in 61 years old female treated by total urethrectomy with resection of corresponding bladder neck, and suprapubic neourethrelization.
