RESUMEN
PURPOSE: To establish normal reference ranges of urinary flow rate related to age, body surface area and voided volume in normal Korean pediatric females, uroflowmetry was performed and analyzed statistically. MATERIALS AND METHODS: Uroflowmetry was performed on total 270 normal pediatric females who ranged in age from 4 to 12 years(mean+/-SD: 7.23+/-1.97 years). The height and weight were measured then body surface area was calculated by Mosteller`s formula. The uroflow data(peak and average flow) were grouped by age(4 to 6, 7 to 9 and 10 to 12 years old) and body surface area( 1.1 and<1.1 m2) then plotted in volume-related nomograms. RESULTS: Mean values of peak and average flow rates were 13.33+/-4.44 & 7.51+/-2.6, 14.01+/-5.22 & 7.76+/-3.15, 20.40+/-6.84 & 10.89+/-3.97 ml/sec in each age group, and 13.57+/-4.87 & 7.61+/-2.96, 20.14+/-6.44 & 10.65+/-3.79 ml/sec in each body surface area group, respectively. Flow rates were increased significantly with voided volume, age and body surface area. Body surface area was found to be a more reliable index than age in the establishment of nomograms(p<0.05). CONCLUSIONS: Nomograms of peak and average flow rates of normal Korean pediatric female were presented. These may be useful for diagnosing lower urinary tract disturbances in pediatric female over a wide range of age, body size and voided volumes.

Complete urethral loss with vesicovaginal fistula is very infrequently encountered by the urologist. Urethral reconstruction may be accomplished with either bladder or vaginal wall flap. Moreover, it usually is necessary to reinforce the continence of reconstructed urethra with a well-vascularized pedicle flap from either the Martius labial flap, gracilis, perineum, or rectus. We report a case of the complete urethral loss with vesicovaginal fistula treated successfully with bilateral Martius labial fat graft.

Polyorchidism is a rare anomaly. It may result from transverse division of the urogenital ridge, a hypothesis that best explains the anatomical features of the supernumerary testicle. Until recently, histology provided the only proof of polyorchidism but new imaging techniques, such as sonography and magnetic resonance imaging(MRI), allows a highly accurate diagnosis of supernumerary testes rendering biopsy unnecessary. We report a case of polyorchidism in a 24 month-old-boy in whom the scrotal sonogram and magnetic resonance imaging confirmed the presence of 2 testicles without any evidence of tumor within his right hemiscrotum and who was treated conservatively and followed up 2 years.

Persistent mullerian duct syndrome is characterized by the presence of mullerian structures in male subiects with normal penile and scrotal development. A deficiency of activity of a mullerian inhibiting substance during gestation is believed to be responsible for this syndrome. To date approximately 150 cases of persistent mullerian duct syndrome have been reported and the syndrome of transverse testicular ectopia with persistent mullerian duct structures is much rarer. In Korea, this is the fourth case to be reported. We report a case of persistent mullerian duct syndrome with transverse testicular ectopia in a 7 month-old-boy. Both testes were in the right side of scrotum but no epididymises were found there, which resulted in the disruption of normal relationship between the was and testis. Regarding there was no fertility, mullerian duct structures were removed.
