The effects of Intraurethral Stent (Intraurethral Cath) for the Treatment of Benign Prostatic Hypertrophy / 대한비뇨기과학회지

Transurethral resection of Prostate(TURP) is the current optimal therapy for benign prostatic hypertrophy. But in some cases of BPH patients, TURP cannot be performed because the patients have medical disorders not to be operated. Thus several alternatives have been used in the management of BPH patients, especially who had anesthetic contraindications to an operation. We experienced 12 cases of BPH patients applied with Intraurethral Cath(IUC) from April 1991 to September 1995. Eleven patients became able to void after IUC insertion. The maximal flow rates were 5.1 to 15.7 ml/sec and average value was 11.8 ml/sec. Almost all patients showed irritative voiding symptoms such as urgency, urge incontinence, frequency, and dysuria at first. In 7 patients, these symptoms disappeared spontaneously within 2 to 5 days and oxybutynin chloride was used orally in 2 patients. Suprapubic cystostomy was done in three patients because two patients had severe irritative voiding symptoms and one patient had persistent urinary retention. The stent was changed every 3 to 6 months. Stone formation around the device was noted in 2 patients and migration of device into the bladder was found in 2 patients. In 4 patients, TURP was performed when the patient's condition improved enough to be operated under epidural anesthesia. In conclusion, the use of IUC is thought to be a valid, cost effective and safe alternative to TURP in the treatment of highly operative risk patients with benign prostatic hypertrophy.

Intrascrotal Lymphangioma 2 Cases / 대한비뇨기과학회지

Intrascrotal lymphangioma is a rare benign lesion of uncertain etiology. A 2-year-old male and a 3-year-old male presented with painful swelling of the right scrotum. After sonographic examination of scrotums, both cases were explored and found to have cystic scrotal masses separated from testes and epididymies. Histopathologic study of the resected specimens confirmed intrascrotal lymphangiomas.

A Case of Persistent Mullerian Duct Syndrome / 대한비뇨기과학회지

Persistent mullerian duct syndrome is an uncommon condition which is a consequence of a defect in either the production or the peripheral action of mullerian inhibiting substance(MIS). We experienced a case of persistent mullerian duct syndrome of a 28 year-old patient who had a testis and female internal genital organs such as mullerian duct remnant in right scrotum with inguinal hernia and an undescended testis in left side. The patient was managed by resection of the left testis and the female internal genital organs such as mullerian duct remnant, and orchiopexy for right undescended testis.

Torsion of Appendix Testis: 14 Cases / 대한비뇨기과학회지

In spite of today's striking development of radiologic studies, the differential diagnosis of acute scrotal diseases is difficult. We studied 14 cases of appendix testis torsion that had visited our hospital from May 1991 to October 1994 in order to be diagnosed accurately and made appropriate treatment. The torsion of appendix testis occurred during prepubertal ages, and ages of our 14 cases were from 3 to 13, and average age was 9.6 years old. In all of our cases the chief complaint was scrotal pain. The localized pain and palpable tender mass of testicular upper pole were present in only 8 of 14 cases and 5 cases had blue dot sign. These were very helpful in diagnosis of torsion of appendix testis. Doppler ultrasonography was done in 9 cases and radionuclide scrotal imaging was done in 3 cases, but none of these studies were diagnosed as torsion of appendix testis definitely. But in 8 cases that had positive blue dot sign and/or localizing tender mass in upper pole of testis, we could diagnose torsion of appendix testis certainly. We operated 11 of l4 cases( scrotal exploration and excision of torsed appendix testis) and treated conservatively 3 of 14. Most 11 operated cases were revealed that scrotal pains were relieved within 24 hours of postoperative period and secondary complications did not occurred in 3 cases treated conservatively. In summary, the early surgical exploration is necessary to improve maximal testicular salvage when testis torsion cannot be ruled out completely in acute scrotal diseases. But if testis torsion can be ruled out completely, conservative treatment may be considered in torsion of appendix testis.

Ureteroscopic Removal of Ureter Stone / 대한비뇨기과학회지

Rigid ureteroscopy is now an established technique for the management of ureteral stones and the diagnostic procedure of ureteral lesions. The results of ureteroscopic stone removal were reviewed in 153 patients (1 patient ; bilateral). From October 1989 to August 1990, 163 patients underwent ureteroscopic removal of ureter stones. There were 53 female and 100 male patients between 17 and 72 years old. In all patients with ureteral stones surgical intervention was indicated for the obstruction with deteriorating kidney function, infection or severe and prolonged pain. All procedures were performed under epidural anesthesia. Stones were extracted, using grasping forceps or stone baskets with or without electrohydraulic lithotriptor (EHL) under direct visual control. Success of ureteroscopic removal was related to the location of the calculus : 98.2% in the distal, 88.2% in mid and 79.2% in the proximal ureter (overall success rate was 94.2% ). The associated number of complications was low, with most patients being treated conservatively. We conclude that ureteroscopic removal of ureteral stone under direct vision can be done safely and be the first choice of management for the ureteral calculi.

A Case of Rhabdomyosarcoma of the Bladder in an Adult / 대한비뇨기과학회지

Recently we experienced a case of embryonal rhabdomyosarcoma of the bladder in a 38 years-old female. She complained of total painless gross hematuria and diagnosis was made by cystoscopy and TUR biopsy. Partial cystectomy and pelvic lymph node dissection performed on July 1989, and then she received the chemotherapeutic agents under the diagnosis of Intergroup Rhabdomyosarcoma Study Group I, the post-operative 8 months, she is in good condition without recurrence of tumor.

A Case of Leiomyoma in the Female Urethra / 대한비뇨기과학회지

Leiomyoma of the urethra is a rare condition, which is more common in female than in male subjects. A case of leiomyoma of female urethra in a twenty-two years old female arising from anterior lip of the external urethral meatus is presented. The presenting symptoms were painless mass on the anterior lip of the external urethral meatus and voiding difficulty. The mass was easily removed by surgical resection and confirmed as leiomyoma histologically.
