Simplified open approach to surgical treatment of ureteropelvic junction obstruction
in young children and infants.
Results of a practical protocol for management of prenatally detected hydronephrosis due to ureteropelvic junction obstruction
. Pediatr Surg Int 2008;25:61-7.
While a third of patients are asymptomatic, renal calculi and ureteropelvic junction obstruction
are common, leading to hydronephrosis.
Congenital anomalies of the kidney and urinary tract are part of a family of diseases with different anatomical origins, including kidney anomalies, such as multicystic dysplastic kidney, hypoplastic kidney, ureteropelvic junction obstruction
, vescicoureteral reflux, megaureter, and anomalies of the bladder and urethra.[sup.1]
Koleda and colleagues studied the density of interstitial cells in ureteropelvic junction obstruction
.[sup.24] The number of fields with few ICC (0-1) was significantly lower in obstructed group than non-obstructed group.
Cost-effective treatment for ureteropelvic junction obstruction
: a decision tree analysis.
In the presence of ureteropelvic junction obstruction
(UPJO), a full-thickness incision was made using a hook knife truly lateral to the UPJ.
Braga and colleagues examined open flank, DL and laparoscopic procedures to treat ureteropelvic junction obstruction
; they also observed that the laparoscopic approach had the longest operative time, but the shortest hospital stay, which is similar to our results.[sup.3] With ongoing increased adoption of LDN, it is likely that LDN operative times will be reduced, and approach that of its open counterparts.[sup.3] Patients in the LDN group lost a significantly lower amount of blood intraoperatively, experienced a lower rate of major and minor complications and spent less time in hospital postoperatively than patients in either the FL or DL groups.
Open dismembered pyeloplasty described by Anderson-Hynes is considered the gold standard to treat ureteropelvic junction obstruction
(UPJO), with success rates exceeding 83%.[sup.1] Muscle-sparing incisions through dorsal lumbotomy provide adequate exposure for UPJO repair, while maintaining minimal convalescence time.
