Long-term bladder function after ureterocele decompression in children.

PURPOSE: There is limited knowledge of long-term bladder function after ureterocele decompression. We studied bladder function in patients who underwent surgery in childhood for duplex system ureteroceles. MATERIALS AND METHODS: Toilet trained children treated for duplex system ureteroceles between 1990 and 2010 were included in study. We evaluated voiding dysfunction by the valid DVSS questionnaire and noninvasive studies, including uroflowmetry, electromyogram and post-void residual urine measurement. Urodynamics were done only in patients with abnormal DVSS or abnormal noninvasive studies. Patients were divided into group 1-ureterocele decompression (endoscopic incision), upper pole partial nephrectomy and ureteropelvic anastomosis, and group 2-primary or secondary bladder surgery (ureterocelectomy, ureterovesical reimplantation and bladder floor reconstruction). RESULTS: Of 62 operated patients 17 were lost to followup and 45 were fully studied at a mean followup of 9.5 years (range 3 to 20). Initial surgery was done at mean age of 5.1 months (range 6 days to 48 months). In the 33 group 1 patients, of whom 70% underwent endoscopic incision, the mean DVSS score was 1.5 (range 0 to 6), 7 patients (22%) had abnormal uroflowmetry or significant post-void residual urine and none had abnormal DVSS results. In the 12 patients in group 2 the mean DVSS score was 4 (range 0 to 11), 8 patients (66%) had abnormal uroflowmetry and significant post-void residual urine, and 3 had abnormal DVSS findings (p = 0.036). All group 2 patients underwent bladder surgery after decompression, including endoscopic incision in 2 and upper pole partial nephrectomy in 1. Only 1 child needed clean intermittent catheterization at age 3 years for hypocontractile megacystis and repeat febrile urinary tract infections. CONCLUSIONS: Ureterocele decompression alone in early childhood does not lead to major bladder dysfunction at long-term evaluation. Even if secondary bladder surgery is needed, significant bladder dysfunction is rare.

Acute respiratory distress for late-presenting congenital diaphragmatic hernia.

Congenital diaphragmatic hernia (CDH) presents a wide spectrum of anatomical variants and clinical pictures depending on the topography and dimensions of the diaphragmatic defect and on the patient age. Most CDH cases acutely present with tachypnea, cyanosis, and respiratory failure within the first minutes to hours of life. Despite significant advances in neonatal medicine, this congenital anomaly still presents a high mortality rate, especially for associated malformations. On the other hand, there is a rare subset of CDH patients who present outside the neonatal period. The most common symptoms of late-presenting CDH include recurrent pulmonary infections, dyspnea, wheezing, abdominal pain, failure to thrive, vomiting, diarrhea and anorexia. Although late-presenting CDH generally presents good prognosis after early surgical correction, misdiagnosis is quite frequent because of its wide spectrum of clinical manifestations. The following case report describes a six-month-old infant presenting with acute respiratory distress and vomiting caused by late-presenting left-sided CDH.
