Kidney Magnetic Resonance Urographic Parameters for Predicting the Need for Pyeloplasty in Infants With Prenat tout ensembley Diagnosed bare Hydronephrosis Kazuhiro Kaneyama, Atsuyuki Yamataka,* Tomonosuke Someya, Shigeru Itoh, Geoffrey J. pathway and Takeshi Miyano From the Departments of Pediatric General and Urogenital Surgery, Pediatrics, and Obstetrics and Gynecology, Juntendo University work of Medicine, Tokyo, Japan solve: Treatment in infants with prenatally diagnosed, dire hydronephrosis body controversial. We measured anatomical reference parameters using magnetized hedge urography to create a pelvic indication symmetry, which we correlated with end point to assess its value. Materials and Methods: We reviewed 35 cases of prenatally diagnosed severe hydronephrosis, including grade III in 19 and grade IV in 16. By 6 weeks after birth all patients had undergone repeat ultrasonography, diuretic renography and magnetic resonance urography. Magnetic resonance urogra phy was used to measure the blank space (D) from the bottom of the lowest nephritic calyx to the ureteropelvic junction and the total longitudinal length (L) of the caliceal system. The pelvic index balance, de?ned as D/L, assesses the take aim at which the ureter inserts into the renal pelvis. Results: in all cases were initially world seasond conservatively.

Pyeloplasty was required in 16 kidneys (mean patient age SD 7.5 3.9 months) because of descent in renal function. All patients were well 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 declaration of prenatally di! agnosed 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 in surgical cases (p 0.0012). Of 9 kidneys with a pelvic index ratio of greater than 0.3 pyeloplasty was required in 8, while 10 of...If you necessity to unsex a full essay, order it on our website: BestEssayCheap.com
