A male child of 9 months with bilateral Wilms tumor was admitted to our hospital. His chief complaint was abdominal mass. Clinical examination and IVP, USG and CT-scan disclosed bilateral Wilms tumor. Right nephrectomy and left partial nephrectomy were performed. Anuria was experienced to 24 hours and so exploratory-laparotomy was done. Renal autotranplantation was performed because of the thrombosis of renal artery. But six days after operation he died.

We performed original and modified technique of Mays' glanuloplasty in 6 and 12 cases respectively. The results were as follows: 1. 6 cases of mild from of hypospadias (2 cases of coronal, 4 cases of dist. penile) and 12 cases of severe form of hypospadias (5 cases of prox. penile, 6 cases of penoscrotal, 1 case of perineal) on pre-chordectomy but all cases became severe from of hypospadias (2 cases of prox. penile, 15 cases of penoscrotal, 1 case of perineal) on post-chordectomy. 2. The postoperative complications were 3 cases (50.0%) (1 case of meatal stenosis, 2 cases of meatal necrosis) in original technique of Mays' glanuloplasty and 2 cases of meatal stenosis (16.7%) in modified technique of Mays' glanuloplasty.

PURPOSE: We describe clinical assessment of visual internal urethrotomy (VIU) as primary treatment modality in 69 men who presented with complete or partial obstructed urethral stricture. MATERIALS AND METHODS: The 63 patients with partial obstructed urethral stricture were treated by typical VIU. The 6 men with complete obstructed urethral stricture were treated by VIU using sound passed through previously placed suprapubic tract as guide. RESULTS: The procedure was completed successfully in 57 of the 63 men with partial obstructed (90.5%) and 3 of 6 patients with complete obstructed urethral stricture (50%). CONCLUSIONS: VIU is a safe and effective as primary treatment plan when urethral stricture is partial obstructed and the impassable urethral segment is shorter than 1.0cm.

Purpose: The ideal neurourophysiologic investigatory technique would objectively and quantitatively evaluate functional status of all parts of the neurologic network involved in obtaining and maintaining penile erection. We assessed electrical activity of the corpus cavernous smooth muscle in normal and neurogenic erectile dysfunction men using SPACE. Material and Methods: A total of 39 normal subjects and 40 neurogenic erectile dysfunction patients underwent single potential analysis of cavernous electricity(SPACE) with a 2-channel EMG amplifier and surface electrodes. The electrical potentials were processed with the cut off frequencies at 0.3 - 32 Hz, a paper speed of 0.5cm/sec, and a range of amplitude of 0.5mV. Results: In 35 of 39 normal subjects(89.7%) and 5 of 10 incomplete suprasacral spinal cord injury patients, similar single potentials of uniform shape were recorded. In patients with peripheral autonomic denervation, irregular shape potentials with higher frequency and lower amplitude were found. In 3 of 5 patients with long standing diabetes(over 15 years), SPACE shows electrical silence. Conclusion: These results suggest that SPACE test is a useful noninvasive and reproducible method for evaluating cavernous innervation in erectile dysfunction. Furthermore, the single potential means intact cavernous innervation.

In situ extracorporeal shock wave lithotripsy(ESWL) monotherapy was performed in 75 cases with ureteral stones using the Modulith SL 20 electromagnetic lithotriptor between December 1990 and July 1991. The results obtained were as follows: 1. The locations of stones were upper ureter in 36 (48%) cases, midureter in 4 (5.3%) and lower ureter in 35 (46.7%). 2. The average number of ESWL was 1.27 sessions. 3. The number of ESWL sessions increased in accordance with increment of stone size. 4. The success rate was 97.2% in upper ureteral. 100% in midureteral, and 97.1% in lower ureteral stones. 5. The final success rate according to stone size was not significantly different. 6. Success rate decreased relatively in cases of complete ureteral obstruction by stones. Therefore, in situ ESWL monotherapy is considered to be a convenient safe, and efficient procedure as the first applicable method for the treatment of all ureteral stones regardless of stone size and location, because the multiple repeated ESWL monotherapy increases the success rate without ureteral deterioration.

The factors influencing upon stone fragmentation by extracorporeal shock wave lithotripsy (ESWL) of ureteral stones are considered to be stone size, location, component, and impaction. ESWL was performed in 322 cases with ureteral stones using the Modulith SL 20 electromagnetic lithqtripter between December 1990 and July 1992. The factors influencing upon stone fragmentation such as stone size, location, degree of hydronephrosis, shape, pain character and presence or absence of urinary tract infaction for the first and second session of ESWL were investigated. The failure rate of ESWL according to stone size was similar for stones smaller than 2.0cm(p>0.05) but was high for stones larger than 2.0cm(p<0.05). The failure rate of ESWL for upper ureteral stones was similar to midureteral stones(p>0.05) but was low for lower ureteral stones(p>0.05). The failure rate of SSWL according to degree of hydronephrosis was similar in cases without hydronephrosis and with mild hydronephrosis(p>0.05) but was high in cases with severe hydronephrosis(p<0.05). The failure rate of ESWL according to stone shape was not significantly different(p>0.05). The failure rate of ESWL in cases without pain was not significantly different from in cases with dull or colic pain(p>0.05). Urinary tract infection did not influence on the failure rate of ESWL(p>0.05). From this study it is believed that factors affecting fragmentation of ureteral stones were stone size, location, and degree of hydronephrosis, but stone shape, presence or absence of pre-ESWL pain or urinary tract infection did not influence on stone fragmentation rate.

A total of 92 men with impotence underwent a trial of intracavernous injection of papaverine 30mg. Underlying causes of impotence were psychogenic (26 Pts.), posterior urethral injury (28 Pts.), spinal cord injury (15 Pts.), pelvic surgery (14 Pts.) and eldly (9 Pts.). The results were as follows 1. The underlying causes of impotence in papaverine responders were psychogenic 23 (88.5%), posterior urethral injury 19 (67.9%), spinal cord injury 13(86.7%), Pelvic surgery 5 (35.7%) and eldly 3 (33.3%). 2. Fourteen patients of the moderate papaverine responders underwent intracavernous injection of papaverine 30mg with phentolamine 1mg and 8 of them attained full erection. 3. After injection, the erection started in an average of 2.6 minutes, rigidity of penis attained in an average of 7.3 minutes, and erection status sustained for an average of 42.6 minutes in 60 patients. 4. Normal nocturnal penile tumescence monitoring (NPTM) or stamp test was found in 19 of 40 patient and 18 of them (94.7%) were papaverine responders, while 21 had an abnormal NPTM or stamp test and 11 of them were papaverine non-respoders. 5. A penile brachial index (PBI) of 0.6 or more was found in 62 of 73 patients and 53 of them(85.5 %) were papaverine responders, while 11 had an index of less then 0.6 and all of them were papaverine non-responders. 6. Thitry patients had sexual intercourse. Twenty-seven of them had a satisfactory result and 23 of them had ejaculation. 7. Papaverine induced prolonged erection occurred as major complicatiun in 4 patients after trial injection. Erection was subsided after intracavernous phenylepinephrine injection. There were minor complications such as ecchymosis at the injected site on the prepuce but subsided spontaneously in a few days. We conclude that intracavernous papaverine injectiun currently is a good screening technique for the differential diagnosis of severe vasculosenic impotence and is a useful chemical prosthesis of non-vasculogenic impotence.

Megaureter literally means a large ureter and is not used to denote a specific disease process. In this report a classification was proposed according to International pediatric urologic seminar in 1976. Seven cases of primary obstructive megaureter were presented with literature. This diagnosis excluded infravesical obstruction, reflux and neurogenic disorders. The results were as follows; 1. 6 cases were left, 1 case was bilateral. 2. The symptom of pyuria was observed in 2 cases, flank pain and pyuria were observed in 2 cases hematuria was observed in 2 cases, abdominal distention was observed in 1 cases. 3. Histologic findings showed inflammation of mucosa and submucosa in 3 cases, submucosal fibrosis and muscular hypertrophy in 2 cases and submucosal fibrosis and inflammation in 2 cases. 4. 6 cases were treated by Politano-Leadbetter ureteroneocystostomy and 1 case of them was tailored 1 case was treated by nephrourethrectomy. 5. Follow up study was performed in 5 cases of Politano-Leadbetter ureteroneocystostomy. 4 cases of them showed improved pyuria and hydroureteronephrosis.
