[Transurethral electroresection of the external urethral sphincter in the urological management of male tetraplegics].

Transurethral electroresection of external urethral sphincter (TUR-sph) was performed in sixteen male tetraplegics to obtain good voiding efficiency and to prevent autonomic dysreflexia due to detrusor sphincter dyssynergia. Ratio of residual urine as a parameter of voiding efficiency and blood pressure and plasma noradrenaline level during voiding as parameters of the significance of autonomic dysreflexia were evaluated before and after TUR-sph, and all these parameters had significantly improved after TUR-sph. After discharge from the hospital, all patients urinated comfortably with the maneuver of suprapubic percussion by themselves and/or their helpmates, and no patients complained of any inconvenience due to urinary incontinence. Moreover, no patients had the episode of autonomic dysreflexia in daily life except for one patient who had it once with urinary tract infection. TUR-sph brings not only the improvement of voiding efficiency but also the effect as a safety valve against autonomic dysreflexia by means of preventing the occurrence of autonomic dysreflexia due to detrusor sphincter dyssynergia.

[Intracavernous injection of papaverine hydrochloride for impotence in patients with spinal cord injury].

Twenty-one intracavernous injections of 40 or 60 mg papaverine hydrochloride were given to ten male paraplegics. Erection sufficient for coitus was achieved within a few minutes after 15 of the injections (71.4%). Tumescence of the penis lasted from 18 minutes to 48 hours and the penile tumescence of the patients who had reflective erection usually lasted longer than that of the patients who did not. The trial that lasted for 48 hours resulted in the fracture of the penis that was presumed to have occurred during coitus and it was treated operatively. Intracavernous injection of papaverine hydrochloride is available for the impotence of male paralegics, but both doctor and patient must be careful about the sensory disturbance of the penis to avoid penile injury during erection. Further studies are needed to establish safety and long-term efficacy, as well as to determine if histological change of cavernous body occurs by repeated injection.

[Urological treatment of patients with spinal cord injury in the chronic stage].

One hundred eighty patients with spinal cord injury were admitted to our hospital between January, 1980 and June, 1983. Eighty-five of them had cervical lesions, 54 had thoracic lesions and 41 had lumbar lesions. Most of the neurogenic bladders due to spinal cord injury treated in our clinic, could be classified into 3 major patterns: hypoactive detrusor-hypoactive sphincter, hypoactive detrusor-active sphincter, and hyperactive detrusor-hyperactive sphincter. To control the hyperactivity of the detrusor and the sphincter, we employed pharmacotherapy first and then we performed transurethral resection of the bladder neck and prostatectomy (TUR-Bn.P) and nerve block (sacral nerve block, pudendal nerve block, obturator nerve block and lumbar nerve block). In the case of a hypoactive detrusor, we employed TUR-Bn.P, open ileal flap fixation to the bladder and voiding training. Using these procedures, we could make 157 patients catheter-free.

[Adrenal cyst: report of a case].

A 32-year-old woman was admitted because of a large abdominal mass in the right upper quadrant. Laboratory findings including hormonal studies were within normal ranges. CT scan and various X-ray examinations revealed a large adrenal cyst on the right side. On May 2, 1984, an adrenal cyst was removed through the right flank incision. Histological study showed that the wall of the cyst consisted of fibrous tissue with endothelial linings and dilated lymphatic vessels. Thus it was classified as a lymphangiomatous adrenal cyst.

[Percutaneous nephrostomy].

Sixty three cases (male 32, female 31) of supravesical obstruction were treated with ultrasonically guided subcutaneous nephrostomy at our hospitals from October 1980 to October 1984. Their age ranges from 2 months to 84 years old, and median age was 52 years old. The major causes of ureteral obstruction were extended pelvic malignancies, 45 cases (71%) (gynecological 18, urological 16, gastrocolorectal 7 and others 4), and benign disease 18 cases (29%). Objectives of nephrostomy were classified in 4 categories (drainage, manipulation, irrigation and evaluation), and results of nephrostomy were discussed for each category. No major complications were observed. Only prolonged macrohematuria (over 48 hours) and fever (over 38 degrees C) were observed in 5 cases respectively. Success rate of nephrostomy placement was 97.5% of all cases. With ultrasonography and angiographic technique, percutaneous nephrostomy is an easy, safe and reliable method.

[Effect of Robaveron tablet (KN-7) in the long-term therapy for urinary disturbances].

Long-term therapeutic effect of Robaveron tablet (KN-7) was studied on 10 female patients of middle and old age with ptosis of urinary bladder and 9 patients with neurogenic bladder. The patients had mainly complained of such subjective symptoms as pollakisuria, difficulty of urination, sense of residual urine, lower abdominal discomfort and urinary incontinence. Robaveron tablet was administered at 2 tablets t.i.d. for 3-26 months. And the drug efficacy was evaluated by residual urine, cystometric findings and subjective symptoms. A significant decrease in the residual urine rate and a significant increase of pressure amplitude were obtained, and improvement of subjective symptoms was seen with an effective rate of about 70%. Overall effectiveness, rated slightly improved or better was 89.5%. No cases of side effects or abnormalities in laboratory tests were observed. Robaveron tablet is safe and effective for patients with urinary disturbance accompanied by ptosis of urinary bladder, as a myogenic disorder, as well as neurogenic bladder in the long-term therapy.

[Clinical study of urothelial tumors of the upper urinary tract. 1: Primary renal pelvic tumors].

Forty primary renal pelvic tumors treated at our University between 1963 and 1981, were reviewed retrospectively. The conclusions of this study are as follows. Sex and age distribution of the patients were 30 males and 10 females (3: 1), and average age was 60.5 years old. The major symptoms were hematuria and flank pain; however, palpable mass was rare. The majority of patients were admitted to our clinic within 6 months from manifestation of symptoms. The major findings of IVP were non-functioning kidney and filling defect. The positive rate of urinary cytology was 46.7%. Total nephroureterectomy with bladder cuff was performed in 20 out of 32 cases. Histologically, 29 cases were transitional cell carcinoma and 4 cases were squamous cell carcinoma with renal calculi. Simultaneous urothelial tumors were seen in 10 cases, 3 in the ureter and 7 in the bladder. A subsequent ureteral tumor was found in one out of 12 cases in which ureters were resected incompletely, and 7 subsequent bladder tumors were found out of 32 cases receiving surgical treatment in the follow-up period. The 5-year survival rate by the actuarial method was 75.9%. Among several factors, grade and stage of the tumor were the most influencing factors for prognosis. An effective method of post-operative treatment could not be established.

[Clinical study of urothelial tumors of the upper urinary tract. 2: Primary ureteral tumors].

Twenty-five primary ureteral tumors treated at our University between 1963 and 1981, were reviewed retrospectively. The conclusions of this study are as follows. Sex and age distribution of the patients were 18 males and 7 females (2.6: 1), and average age was 63.04 years old. The major symptom was hematuria. The majority of the patients were admitted to our clinic within 6 months from manifestation of symptoms. The major finding of IVP was non-functioning kidney. The positive rate of urinary cytology was 63.2%. Total nephroureterectomy with bladder cuff was performed in 21 out of 23 cases. Histologically, 22 cases were transitional cell carcinoma and one case was squamous cell carcinoma. Simultaneous urothelial tumor was found in 13 cases in the bladder. Most of the ureteral tumors (63.6%) were found in the lower third segment of the ureter. Subsequent urothelial tumors were seen in 3 bladders and one urethra out of 22 cases receiving surgical treatment in the follow-up period. The 5-year survival rate by actuarial method was 39.4%. Among several factors, grade and stage of tumor were the most influencing factors for prognosis. An effective method of post-operative treatment could not be established.
