The Safety of Pyeloplasty in Premature and Mature Neonates / 대한비뇨기과학회지

The widespread use of antenatal ultrasonography has resulted in an increasing number of newborns being diagnosed with hydronephrosis. In general, the potential of recovery in an obstructed kidney detected by maternal antenatal ultrasonography cannot be predicted by the currently available diagnostic means. Thus the urgency,safety and benefits of performing pyeloplasty in neonates currently are being questioned. To evaluate the anesthesiologic risk and the surgical morbidity of pyeloplasty in premature and mature neonates with hydronephrosis requiring surgical correction, the premature and mature neonates who underwent surgical correction were classified into 3 groups. First two groups are the infants under and beyond 1 month of age who underwent an operation without preliminary percutaneous nephrostomy and the third group is composed of the infants who underwent corrective surgery one month after preliminary percutaneous nephrostomy which was performed during neonatal period. There was no remarkable difference in anesthetic time, operation time, duration of postoperative hospital day and surgical complication among groups. The surgical results in all except 1 case showed the definite morphological and functional improvement of kidney. Pyeloplasty in premature and mature neonates is a safe and successful procedure for presentation of renal function as the procedure performed in older age group.

Two Cases or Primary Small Cell Carcinoma of the Prostate / 대한비뇨기과학회지

Small cell carcinoma of the prostate is rare, accounting for approximately 1% of all prostatic cancer. However the identification of small cell carcinoma of the prostate has increased in recent years, probably reflecting the increasing use of the electron microscope and immunohistochemistry. We report a case of pure small cell carcinoma and a case of small cell carcinoma mixed with adenocarcinoma of the prostate.

Two Cases of Extragonadal Embryonal Carcinoma Originating in Unusual Sites / 대한비뇨기과학회지

Primary germ cell tumor of extragonadal origin are rare, accounting for approximately 3 to 5 percent of all germ tumors. Extragonadal germ cell tumors usually originate in midline body structures. We report a case of extragonadal germ cell tumor from the left superficial inguinal area, a nonmidline structure and a case of from the superficial suprapubic area unusual site of extragonadal germ cell tumor-with brief of the literature.
