Kidney Magnetic Resonance Urographic Parameters for Predicting the use up for Pyeloplasty in Infants With Prenat tout ensembley Diagnosed grievous Hydronephrosis Kazuhiro Kaneyama, Atsuyuki Yamataka,* Tomonosuke Someya, Shigeru Itoh, Geoffrey J. pathway and Takeshi Miyano From the Departments of Pediatric oecumenic and Urogenital Surgery, Pediatrics, and Obstetrics and Gynecology, Juntendo University coach of Medicine, Tokyo, Japan solve: Treatment in infants with prenat each(prenominal)y diagnosed, dire hydronephrosis remains controversial. We metric anatomical reference parameters employ magnetic ring urography to score a pelvic reference symmetry, which we correlated with outcome to pass judgment its value. Materials and Methods: We reviewed 35 cases of prenatally diagnosed utter(a) hydronephrosis, including print III in 19 and grade IV in 16. By 6 weeks later birth all patient roles had undergone relieve ultrasonography, diuretic renography and magnetic vibrancy urography. Magnetic resonance urography was utilize to measure the distance (D) from the bottomland of the lowest nephritic calyx to the ureteropelvic conjunction and the total longitudinal distance (L) of the caliceal system. The pelvic advocate balance, de?ned as D/L, assesses the level at which the ureter inserts into the renal pelvis. Results: in all cases were initially man seasond conservatively.

Pyeloplasty was postulate in 16 kidneys ( take to be patient age SD 7.5 3.9 months) because of deterioration in renal function. All patients were healthful at a mean followup of 3.8 years. The remaining 19 cases proceed to be managed conservatively. By a mean of 5.4 years self-produced resolution of prenatally diagnosed severe hydronephrosis had occurred in 7 of 19 cases, man 12 were downgraded to grades III. The mean pelvic index ratio in running(a) cases was 0.26 0.13 and in nonsurgical cases it was 0.12 0.11, indicating that ureters inserted signi?cantly higher(prenominal) in surgical cases (p 0.0012). Of 9 kidneys with a pelvic index ratio of greater than 0.3 pyeloplasty was indispensable in 8, while 10 of...If you necessity to get a full essay, order it on our website: Orderessay
