  • LONGITUDINAL PREPUTIAL PEDICLED FLAP URETHROPLASTY FOR CHORDEE OF Donnahoo TYPE IV

    Objective To investigate the effectiveness of longitudinal preputial pedicled flap urethroplasty for chordee of Donnahoo IV type. Methods Between June 1994 and October 2011, 30 patients with chordee (Donnahoo type IV) underwent longitudinal preputial pedicled flap urethroplasty. The patients’ age ranged from 2 to 16 years (mean, 5.8 years). The morphology of the balanus-navicular fossa-external urethral orifice ranged normal; the penis length was 2.5-6.8 cm (mean, 4.3 cm); the penis bending angle was 35-70° (mean, 40.1°). Primary and secondary operation was 27 cases and 3 cases, respectively. The size of flap ranged from 1.5 cm × 1.3 cm to 4.0 cm × 2.0 cm. Results After correction, the penis length was 3.0-8.5 cm (mean, 6.6 cm); the penis bending angle was 0-10° (mean, 1.2°). All patients were followed up 6 months to 12 years (mean, 33 months). No recurrence, stabbing pain of the balanus, or foreign body sensation occurred during follow-up. Of them, 4 patients (13.33%) had urinary fistular, they had satisfactory results after the second operation; 2 patients (6.67%) had urethral stricture 1 month after operation, they also had satisfactory results after arethral dilatation. The other patients showed no scattering urinary flow and good direction without complication. Six patients had satisfactory sexual function after puberty without erection disorder, pain, or dyspareunia. Conclusion Longitudinal preputial pedicled flap urethroplasty can achieve maximum utilization of prepuce and aesthetic and functional improvement with less complication, so it is a relatively ideal mean for treating chordee of Donnahoo type IV.

  • CLINICAL EXPERIENCE IN DIAGNOSIS AND MANAGEMENT OF COMPLETE DUPLICATION OF KIDNEY AND URETER IN 106 CHILDREN

    ObjectiveTo discuss the clinical classification and treatment protocols of complete duplication of kidney and ureter in children. MethodsBetween March 2000 and February 2015, 106 children with complete duplication of kidney and ureter were treated, and the clinical data were retrospectively analyzed. Of them, there were 11 boys and 95 girls, aged from 1 month to 11 years (mean, 3.5 years); one side was involved in 88 cases and two sides in 18 cases. They were divided into 4 types according to image examinations and clinical presentations:14 patients who needed no special treatment were classified into the first type, 15 patients who underwent reconstruction into the second type, 74 patients who underwent segment removal of renal dysplasia and subtotal excision of abnormal duplicated ureter into the third type, and 3 patients who underwent removal of the whole affected kidney and subtotal excision of whole ureter into the forth type. ResultsThe patients were followed up 2 months to 14 years (median, 23 months). There was no deteriorating case in the first type. There was no complication such as leakage of urine, discomfort over the back and loins, ureterocele, reproductive tract infection, or hematuresis in the other types. The results of white blood cell count, renal function, and electrolyte presented no abnormality. One patient in the second type and 6 patients in the third type had ureteral stump syndrome; 1 patient in the second type and 3 patients in the third type had urinary tract infection; and 3 patients in the second type had mild hydronephrosis after operation. ConclusionIt can obtain good clinical outcome to choose individualized treatment according to clinical classification of complete duplication of kidney and ureter, which can reserve effective renal units as much as possible and improves the patients' quality of life.

  • OBSERVATION OF EFFECTIVENESS OF THORACOSCOPIC SURGERY FOR LATEPRESENTING CONGENITAL DIAPHRAGMATIC HERNIA

    ObjectiveTo explore the effectiveness of thoracoscopic surgery for treating late-presenting congenital diaphragmatic hernias and summarize the experience. MethodsBetween October 2012 and February 2015, 21 children with late-presenting congenital diaphragmatic hernias underwent thoracoscopic surgery. Of the 21 cases, 12 were girls and 9 were boys with a median age of 1 year and 3 months (range, 2 months to 8 years). Eight patients had obvious symptom in the initial stage:shortness of breath and dyspnea; 13 cases were found occasionally through chest radiography. Of 21 cases, 17 had left diaphragmatic hernias and 4 had right diaphragmatic hernias. The emergency surgery was performed in 5 cases because oppressed obviously and selective operation in 16 cases. Hernial sac existed in 5 cases; there were 19 cases of Bochdalek's hernia and 2 cases of Morgagni's hernia. The size of diaphragmatic defect ranged from 3 cm×2 cm to 5 cm×5 cm. ResultsThe operation time was 35-80 minutes (mean, 50 minutes), and intraoperative blood loss was 3-5 mL (mean, 3.8 mL). Primary healing of incision was obtained. Postoperative abdominal distension and pneumothorax occurred in 12 and 2 cases respectively. The follow-up time was 1-3 years (mean, 20 months). All the cases had a good recovery and satisfactory appearance of the thoracic incision. The symptoms and signs of shortness of breath and dyspnea disappeared. There was no recurrence and chest infection. ConclusionUnder the conditions of mastering operative indications strictly, thoracoscopic repair for late-presenting congenital diaphragmatic hernia is safe and feasible. It can facilitate the procedure and decrease the recurrence rate relying on intraoperative application of hernia repair needle, knot pusher-assistant, and reasonable processing defect periphery.

  • MODIFIED Politano-Leadbetter REIMPLANTATION FOR TREATMENT OF CONGENITAL MALFORMATION OF VESICOURETERAL JUNCTION IN CHILDREN

    ObjectiveTo explore the effectiveness of modified Politano-Leadbetter reimplantation for the treatment of congenital malformation of the vesicoureteral junction in children. MethodsA retrospective analysis was made on the clinical data of 53 patients with congenital malformation of the vesicoureteral junction treated with modified Politano-Leadbetter reimplantation between June 2000 and October 2014. Of 53 cases, there were 24 boys and 29 girls, aged from 8 months to 7 years (mean, 2.1 years); 23 had congenital vesicoureteral junction obstruction (14 left, 5 right, and 4 bilateral), and 30 had vesicoureteral reflux (12 unilateral, 18 bilateral), which were verified by voiding cystourethrography. The disease duration was from 1 month to 1 year (mean, 5 months). ResultsAll of the patients underwent modified Politano-Leadbetter reimplantation successfully. The mean operation time was 74 minutes (range, 65-85 minutes) for unilateral cases and 105 minutes (range, 98-130 minutes) for bilateral cases. There was no dysuria, infection of incision, or incision dehiscence after urinary catheter removal. The follow-up time was 6 months to 14 years (median, 28 months); all patients were free from complications of fistula, vesicoureteral reflux, vesicoureteral junction obstruction, or hypertension. The new ureteral orifices had good appearance at 1 month after operation. Urologic ultrasound showed that hydronephrosis relieved at 3 months after operation. Urinary tract infection rate was 13.2% (7/53) during 6 months after operation, which was cured by antibiotics. Voiding cystourethrography showed no vesicoureteral reflux in 32 cases at 6 months after operation. ConclusionThe modified Politano-Leadbetter reimplantation simplifies the operation course, which has the longitudinal ureter after operation and is similar to physiological state. It is a safe and effective option for congenital malformation of vesicoureteral junction in children with few complications, especially for patients with unilateral megaloureter.
