OBJECTIVE Hydronephrosis developing following ureteroscopy (URS) is an important issue associated with the long-term postoperative renal functions. Studies investigating the role of postoperative imaging revealed conflicting results. In this study, we aimed to determine the incidence and predictors of hydronephrosis following semirigid URS. MATERIAL AND METHODS We evaluated the results of 455...

OBJECTIVES To investigate the impact of preoperative hydronephrosis and flank pain on prognosis of patients with upper tract urothelial carcinoma. METHODS In total, 472 patients with upper tract urothelial carcinoma managed by radical nephroureterectomy were included from Kaohsiung Medical University Hospital Healthcare System. Clinicopathological data were collected retrospectively for analy...

OBJECTIVE Antenatal hydronephrosis is diagnosed in 1% to 5% of all pregnancies; however, the antenatal and postnatal management of hydronephrosis varies widely. No previous studies define the risk of postnatal pathology in infants with antenatal hydronephrosis. Our objective was to review the current literature to determine whether the degree of antenatal hydronephrosis and related antenatal ul...

BACKGROUND Infants with neonatal hydronephrosis and a normal voiding cystourethrogram (VCUG) are presumed to have ureteropelvic junction obstruction (UPJO). There is little current information about the natural history of children with hydronephrosis or clinical factors that predict resolution of the radiological abnormality. OBJECTIVE To determine the time course until spontaneous resolution...

background : hydronephrosis (hn) or calycial dilatation is the most common prenatal urologic abnormality. the aim of this study was to identify the possible changes in demographic and clinical manifestations of infantile hn in previously and recently diagnosed patients.   methods : 193 children with infantile hn admitted to ali-asghar children's hospital in two different periods (group 1 1997-2...

BACKGROUND Urinary tract obstruction and postoperative hydronephrosis are risk factor for renal function deterioration after orthotopic ileal neobladder construction. However, reports of relationship between transient hydronephrosis and renal function are limited. We assess the influence of postoperative transient hydronephrosis on renal function in patients with orthotopic ileal neobladder con...

Hydronephrosis means dilation of the pelvis of the kidney by urine which has accumulated, because of obstruction of the urinary tract at some point distal to the pelvis, most commonly the pelvi-ureteral junction. If the obstruction be at a lower level, the ureter becomes dilated first, and the kidney is involved later. Occasionally the obstruction is confined to one or more of the minor calyces...

OBJECTIVE To identify the molecular basis for prenatally suspected cases of megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) (MIM 249210) in 3 independent families with clinical and radiographic evidence of MMIHS. METHODS Whole-exome sequencing (WES) and Sanger sequencing of the ACTG2 gene. RESULTS We identified a novel heterozygous de novo missense variant in ACTG2 c.770G>...
