Background : Ureteric reimplantaion is a common pediatric urological procedure . The standard procedure (politano-leadbetter) had excellent success rate.Tow to six months after surgery most surgeons routinly do a voiding cystourethrogram and renal sonography to confirm the results of surgical correction of reflux and to evaluate the outcomes of operation. In our study we assess the necessity for and efficacy of voiding cystourethrography after uncomplicated ureteral reimplantaion performed for primary VUR in children. Objectives: to evaluate the patients in our practice to determine whether postoperative voiding cystourethrographywas useful in monitoring the outcome after ureteric reipmlantation. Surgical repair of VUR is the treatment of choice after failure of medical therapy, also in high grade reflux. Radiographic evaluation by ultrasonography or VCUG is commonly used post operatively to evaluate for urinary tract obstruction or persistent reflux. However, imaging modalities are not without cost,both in monitoring term and in term of radiation exposure and trauma to the child. Patients and method: Twenty –five patient with 35 refluxing renal unit {primary idiopathic VUR}with their age between 8 month to 12 years (mean age 4.7 y), 5 female (20%),20 male (80%),with high grade VUR grade 4, 5 patients(20%),grade 5 reflux 20 patient(80%), all patients with primary reflux excluding secondary reflux. These patients treated by open intavesical (politano-leadbetter) reimplantation from 2018 to 2020 in urology department at hilla teaching hospital at Babylon and followed for aminimum 1 year by VCUG and ultasonography.VUR was unilateral in 15 patient(60%), and bilateral in 10 patients(40%). Results: The success rate of our prospective study about (72%) of patients show no reflux (18 patients), 4 patients showed grade 1 reflux (16%), 3 patients showed ureteric obstruction(12%) during the initial post-operative follow up (first 3 months)by VCUG . Thenduring follow up for 1 year , the success rate increase to (88%) that 22 patient showed resolution of reflux. Grade 1 reflux only in 1 patients(4%) and ureteric obstruction only 2 patients(8%),that confirmed later by IVU. Conclusions : since the success rate of ureteric reimplantation was high when done by experience urologist ,so the role of VCUG can be omitted to only complicated cases. So that cost saving and decrease trauma to the child and risk of radiation.
