“…In most patients (83.4%), drainage improved after surgery, which was similar to the findings of a recent study. 21 It is essential to confirm the residual obstruction through timely follow up after surgery to prevent the loss of renal function. Diuretic renography is used to confirm relative renal function after pyeloplasty and to ensure proper drainage.…”

Objective To evaluate the clinical value of preoperative ultrasound parameters for post‐pyeloplasty outcomes in pediatric patients with ureteropelvic junction obstruction. Methods The medical records of 187 pediatric and adolescent patients who underwent pyeloplasty as a result of ureteropelvic junction obstruction between 2010 and 2016 were retrospectively reviewed. The severity of hydronephrosis was measured by the Society for Fetal Urology grade, anteroposterior pelvic diameter, urinary tract dilation, hydronephrosis index, and the hydronephrosis area to renal parenchyma ratio at 3, 6 and 12 months. Adverse renal function outcome was defined as ≥10% decrease in postoperative differential renal function compared with preoperative values. Results Of the 187 patients, preoperative hydronephrosis was categorized as Society for Fetal Urology grade 3 in 26 patients (13.9%) and grade 4 in 161 patients (86.1%). No surgical failures, defined as requirement of repeat surgery or deterioration of hydronephrosis grade, were noted. The mean changes in Society for Fetal Urology grade, anteroposterior pelvic diameter, urinary tract dilation and hydronephrosis area to renal parenchyma ratio showed similar trends of recovery during the follow‐up period. In total, 19 patients (10.2%) showed >10% decrease in differential renal function during follow up (mean 42 months). Multivariate logistic regression analysis showed that the hydronephrosis area‐to‐renal parenchyma ratio was the only significant prognostic factor for adverse renal function outcome (hazard ratio 1.806, 95% confidence interval 1.210–2.859, P = 0.005). Receiver operating characteristic analysis showed that the hydronephrosis area‐to‐renal parenchyma ratio was the most significant predictive value (area under the curve 0.711, 95% confidence interval 0.618–0.804, P = 0.006). Conclusions Pediatric patients with high hydronephrosis area‐to‐renal parenchyma ratio values before surgery are more likely to show renal function decline after pyeloplasty.

“…Also, we saw significantly improved ambulation in LP group, which led to early discharge of patients and shorter hospital stay, also confirmed by Mazhar Memon et al [9] The purpose of pyeloplasty (OP and LP) operations in UPJO is to avoid renal complications. There is a lack of consensus on the pre-eminent type of surveillance procedure timing and frequency for the postoperative monitoring of a patient [13]. The failure of laparoscopic pyeloplasty can be early or late.…”

The aim of the study was to compare the clinical and patient-reported outcomes among open pyeloplasty (OP) and laparoscopic pyeloplasty (LP) patients. Materials and methods This was a prospective single centre, case-cohort study conducted in a tertiary care hospital with 62 patients. In both techniques, dismembered Anderson-Hynes pyeloplasty were undertaken. Post-operatively patients underwent visual analogue scale (VAS) assessment for pain, days to ambulation and comparison of the short-and long-term outcomes of the two procedures. Results There was no difference in the physical and functional outcomes between the two surgical approaches at 12 months period after surgery. However, patients in the laparoscopic group did report a higher rate of satisfaction at six weeks and six months' postoperatively. Likewise, patients in LP experienced less pain during the postoperative period (p-value <0.001), with decreased analgesic requirements. This translated into an early patient ambulation in the laparoscopic group (p-value <0.001), and a shorter hospital stay for the LP group (p-value <0.001). Moreover, follow-up ultrasound showed equal improvement of hydronephrosis among the two groups. Conclusion Laparoscopic and open pyeloplasty are equally effective in treating pelvic ureteric junction obstruction (PUJO), with comparable patient-reported outcomes at 12-month follow-up. However, the laparoscopic technique merits over open surgery with faster rehabilitation, a decreased postoperative pain experience and shorter hospital stay.

“…Kumar M et al reports >5% improvement in low SRF (<40%) after pyeloplasty in 41–46% of patients retaining improved renal function after 5 years of follow-up [18]. Another study demonstrated significant increase in SRF in 75% of children whose SRF was impaired preoperatively, but just in early renograms (7–9 weeks postoperatively) [19]. Surgical indications still remain extremely different, varying from active surveillance and delayed pyeloplasty to early surgical management [20,21].…”

Diuretic Enhanced Ultrasonography in the Diagnosis of Pyeloureteral Obstruction

et al. 2019

Background and Objectives: To determine the value of diuretic ultrasonography for the diagnosis of obstructive hydronephrosis. Materials and Methods: Diuretic enhanced ultrasonography was used routinely as a part of examination of patients with hydronephrosis in our Department. There were 72 patients (42 males, 30 females; aged 2 months to 17 years; median age 7.07 years) with a sonoscopic diagnosis of hydronephrosis included from January 2006 until October 2011. The anteroposterior diameter (AD) of renal pelvis was measured sonoscopically before and at sixty minutes after furosemide injection. A weight-adjusted dose of 1 mg/kg of furosemide was administered intravenously. Results: Patients were operated on if pyeloureteral obstruction was suspected because of low or deteriorating differential renal function, increasing hydronephrosis or symptoms thereof. Hydronephrosis was unilateral in 61 (84.7%) and bilateral in 11 (15.3%) patients. The median AD of pelvis before furosemide injection was 22 mm in operated and 17 mm in non-operated patients (p = 0.005). Sixty minutes after furosemide injection, the AD of pelvis in operated patients was 35.5 mm and 25.8 mm in non-operated—25.8 mm (p < 0.001). Logistic regression model demonstrated that significant factors for surgery were: AD 60 min after furosemide infection and ultrasonographic parenchymal sclerosis. Conclusion: Ultrasound measurement of the AD of renal pelvis 1 h after the injection of furosemide used as an additional investigation can help in predicting obstructive hydronephrosis.
