Neonatal urologic urgencies are any genitourinary condition during the 1st month of life that jeopardizes the gonads, the kidneys, or the life of the infant if there is a delay in either diagnosis or treatment. Since 1991, we have experienced 41 cases of neonatal urologic urgencies. Of 41 cases, 23 were detected prenatally. Male to female distribution was 29 to 12. The initial symptoms or signs at presentation were antenatal hydronephrosis in 21, fever in 10, scrotal mass in 5. The rest 5 were 1 abdominal mass, 1 cystic adrenal mass, 1 absence of kidney, 1 abnormal micturition and 1 jaundice. The final diagnosis were 1 neuroblastoma, 2 multicystic dysplastic kidney, 1 multicystic dysplastic kidney and contralateral UPJO, 2 unilateral transient hydronephrosis, 3 bilateral transient hydronephrosis, 1 unilateral renal hypoplasia and contralateral hydronephrosis, 1 unilateral and 2 bilateral UPJO, 1 renal agenesis, 5 complete duplicate ureter, 3 primary megaureter, 1 unilateral UVJ0, 2 unilateral and 9 bilateral VUR, 1 PUV, 1 congenital megalourethra with bilateral hydronephrosis, 1 acute epididymitis, 3 torsion of spermatic cord, 1 cystic teratoma. Surgical treatment was performed in 26 and conservative management in 15. Since it has been reported 2/3 of all infant deaths occur during the 1st year of life, especially most are during the neonatal period, we believe it is crucial that urologists be involved in the care of newly born infants and be alert to the clues of underlying genitourinary abnormalities or diseases because the least easily recognizable urologic abnormality may be the one that requires the most immediate attention in the neonate.

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.

Pseudomyxoma peritonei is a poorly understood condition characterized by mucinous ascites and multifocal peritoneal mucinous tumors. Pseudomyxoma peritonei is most commonly associated with mucinous tumors of the ovary and appendix. When two lesions are morphologically similar, it is difficult to determine whether one reflects a metastasis or whether the tumors are independent. Many studies concluded that most cases in which both the appendix and ovary were involved were primary appendiceal tumor with secondary involvement of the ovary, but we have experienced one case of pseudomyxoma peritonei originated from independent primary borderline mucinous tumors of the ovary and appendix. So we report this case with the brief review of literatures

Interrupted aortic arch is a extreme type of coarctation of aorta and mostly associated with other cardiac anomalies. Unless there were no proper management, about 90% of babies would be dead in their neonatal period. A 28-year-old nulliparous woman was refered to our hospital for fetal echocardiography at 23 weeks' gestation with an abnormal prenatal ultrasonographic findings. We found interrupted aortic arch(type A), which was located in distal portion of the left subclavian artery, and ventricular septal defect. After 5 months follow up, the baby was vaginally delivered at 40 weeks' gestation. This baby was delivered at 40 weeks' gestation of a male infant with APGAR scores of 8 and 9 at 1 and 5 minutes, respectively. Neonatal echocardiography and electron beam tomography revealed interrupted aortic arch(type A), ventricular septal defect(subaortic type), patent ductus arteriosus, and atrial septal defect(ostium secondum defect). At the 10th day of birth, the infant was performed the operation of end to end anastomosis of desending aorta, patch repair of atrial septal defect, ligation of patent ductus arteriosus, and direct closure of patent foramen ovale.

PURPOSE: The prevalence of prostate cancer is increasing in the general population. This study aimed to determine the prevalence of prostate cancer in the general population of Kangseo-Gu, Busan, Korea and to estimate the overall prevalence of prostate cancer in Korea. MATERIALS AND METHODS: We studied 497 community volunteers of a random selection from August to September 2001. The included volunteers were older than 50 years and were not within the area of general urologic practice. Screening protocols included International Prostatic Symptom Score(I-PSS), digital rectal examination(DRE) and serum prostate specific antigen(PSA) with an immunoenzymatic assay(Tandem-E). Transrectal ultrasound guided prostate biopsy was recommended in patients with a PSA value higher than 4ng/ml, suspicious nodules on DRE or a hypoechoic region on TRUS, or more than two of these findings. RESULTS: The mean age of the volunteers was 61.0 years old with a range of 50-88 years. The most common age range for men was 50-54 years old in Kangseo-Gu with a total of 144 men(28.3%). Overall, the age distribution of Kangseo-Gu residents was similar to that of the study population. Estimated prostate cancer prevalence was 1.81%, and 9 out of the 497 men were diagnosed with prostate cancer based on prostate biopsy. CONCLUSIONS: Our study indicated prostate cancer detection rate of 1.8% in Kangseo-Gu which translates to an estimated 77,400 men who suffer from prostate cancer in Korea. This result reflects an increase in the prevalence of prostate cancer of 43% in 2002 as compared with the reported value of 1.27% in 1996.

PURPOSE: Vasectomy has become a popular method for male sterilization in Korea and this, in turn, has been followed by an increase in the number of patient requiring vasectomy reversal. Recently, many authors have reported high success rates of vasovasostomy using microsurgical techniques. The purpose of this study was to compare patency and pregnancy rates and operation time of a new method for vasovasostomy developed at the Department of Urology, Dong-A University Hospital with those of other methods, and to find out other factors influencing patency and pregnancy rates. MATERIALS AND METHODS: Microscopic vasovasostomy was performed in 149 patients from June 1990 to September 1997 at our department. Among 89 patients who could be followed up post-operatively, standard two layer vasovasostomy was performed in 22 patients, modified one layer vasovasostomy with 4 full thickness sutures in 32 patients and modified one layer vasovasostomy with 5 full thickness sutures developed at our department in 35 patients. We compared mean operation times and patency and pregnancy rates between the techniques and examined patency and pregnancy rates according to age, vasal obstruction interval, presence of sperm in vas fluid and sperm granuloma. RESULTS: Success rates were 95.5% for patency and 68.2% for pregnancy in standard two layer vasovasostomy, 87.5% for patency and 59.42% for pregnancy in modified one layer vasovasostomy with 4 full thickness sutures and 97.1% for patency and 65.7% for pregnancy in modified one layer vasovasostomy with 5 full thickness sutures and there was statistical significance in the patency rates between each method (p<0.05). Mean operation times were 136.6+/-19.2 minutes in standard two layer vasovasostomy, 86.6+/-16.8 minutes in modified one layer vasovasostomy with 4 full thickness sutures and 96.7+/-18.4 minutes in modified one layer vasovasostomy with 5 full thickness sutures (p<0.001). With regard to factors influencing operation, the pregnancy rates were slightly higher in cases of younger patients, presence of sperm in vas fluid and presence of sperm granuloma (p>0.05) and significantly lower in case of longer vasal obstruction interval (p<0.0005). CONCLUSIONS: We found little difference in success rates between standard double layer vasovasostomy and modified one layer vasovasostomy with 5 full thikness sutures and the latter was easier and more time saving technique.

PURPOSE: As growth hormone was reported to improve cavernosal nerve regeneration, we studied the action mechanism of growth hormone(GH) on the regeneration of nitric oxide synthase(NOS)-containing penile nerves after unilateral cavernous nerve neurotomy in rats. MATERIALS AND METHODS: Male rats were divided into three groups: sham operation(n=10); unilateral neurotomy of a 5mm segment of the cavernous nerve(n=10) and unilateral neurotomy with GH injection(n=10). Electrostimulation of the intact cavernous nerve was performed at 1 and 3 months after operation. Nicotinamide adenine dinucleotide phosphate(NADPH) diaphorase staining was used to identify nNOS in penile nerve fibers of the mid-shaft segment. The gene expression for nNOS, insulin like growth factor(IGF)-I and nerve growth factor(NGF) were investigated in corporal tissue by reverse transcriptase-polymerase chain reaction(RT-PCR) using specific oligonucleotide primers. RESULTS: Electrostimulation in the GH-treated group revealed a greater maximal intracavernosal pressure and a shorter latency period than in those given neurotomy alone at 3 months after operation. One month after unilateral neurotomy, both neurotomy alone and the GH-treated groups showed a significant decrease in NOS-containing nerve fibers in the dorsal and intracavernosal nerves on the side of neurotomy, however mRNA expression of nNOS and IGF-I showed a significant increase in GH-treated group. At 3 months, the number of NOS-containing nerve fibers in the neurotomy alone group did not increase while the GH-treated group showed a significant increase. CONCLUSIONS: These results show that GH significantly enhances the regeneration of NOS-containing fibers in the dorsal and intracavernosal nerves after unilateral cavernous nerve injury via IGF-I.
