Abstract
Introduction: Posterior urethral valves are a congenital anomaly, which is performing by obstructive membranes in the posterior urethrae and it is shown with extreme dilatation of the upper urine tract . The frequency of PUV is 1 in 5000-12,500 live born child. Despite optimal treatment of PUV, almost one third of the patients may have renal insufficiency.
Objectives: To present a case report of a child with reflux megaureter on the left side, posterior urethral valves, and right renal hypoplasia. In this case, we performed LAP low LOOP ureterocutaneostomy on the same side as the surgical treatment and the benefits of the technique.
Materials and methods: At 1st month of age, the child is diagnosed with PUV, bilateral dilatation of the upper urine tract and right renal hypoplasia, after that is performed resection of the PUV. The postoperative ultrasound shows persistence of the left hydronephrosis and megaureter and reduction of right kidney size. After those results, we performed DTPA scan and voiding cystourethrography, with results of persisting obstructive uropathy of the left side and right renal hypoplasia. Also, we found Reflux VUR on the left side. We performed cystotonometry with elevated tonus of the bladder and lab results og high levels of serum creatinine and urea. Persisting uroinfections and imaging results motivate us to perform LAP Low LOOP ureterocutaneostomy.
Results: No intra- and postoperative complications were observed. Serum levels of creatinine and urea returned to normal levels after 6 months. When we perform control imaging studies after 6 months, we find that the left kidney has increased its function.
Discussion: The correction and postoperative follow-up in patients with PUV are very important for long-term results. Using of LOOP technique in this case of one-sided reflux megaureter is appropriate, because of less surgical trauma and saving the ureterovesical junction, which is important for good postoperative results.
