“…However, it should be emphasized that as the duration of Double J stent placement shortens, its efficacy of urinary drainage and relief of ureteral edema will also be weakened, which may increase the risk of upper urinary tract obstruction tract infection and renal function impairment. The significance of shortening stent indwelling time differs from patient to patient, [ 18 ] and there is a lack of relevant studies to verify the optimal indwelling time. Thus, more relevant studies are needed.…”

To explore the risk factors and develop a nomogram to predict Double J stent encrustation incidence. The general demographic characteristics and underlying risk factors of 248 patients with upper urinary tract calculus who underwent endoscopic lithotripsy and Double J stenting at the Fifth Affiliated Hospital of Sun Yat-Sen University between January 1st, 2018 and January 1st, 2023 were retrospectively analyzed. Among them,173 patients were randomly selected to form the development cohort. A multivariate logistic regression model was employed to identify the independent risk factors associated with Double J stent encrustation, and a nomogram was developed for predicting its occurrence. Additionally, 75 patients were randomly selected to form the validation cohort to validate the nomogram. Multivariate logistic regression analysis revealed that several factors were significantly associated with Double J stent encrustation: indwelling time (odds ratio [OR]1.051; 95% confidence interval [CI] 1.030–1.073, P < .001), urine PH (OR 2.198; 95% CI 1.061–4.539, P = .033), fasting blood glucose (OR 1.590; 95% CI 1.300–1.943, P < .001), and total cholesterol (OR 2.676; 95% CI 1.551–4618, P < .001).Based on these findings, A nomogram was developed to predict the occurrence of Double J stent encrustation. The nomogram demonstrated good performance with an area under the curve of 0.870 and 0.862 in the development and validation cohorts, respectively. Furthermore, the calibration curve indicated a well-fitted model. We constructed and validated an accessible nomogram to assist urologists in evaluating the risk factors associated with Double J stent encrustation and predicting its likelihood.

“…Monitoring changes in renal cortical thickness serves as a valuable indicator of the success of pyeloplasty and the overall health of the kidney. 13 But there is a lack of research on our population. The results can be variable across the populations due to genetic and ethnic factors and clinicians skills.…”

OBJECTIVES To determine the effect of pyeloplasty on renal cortical thickness in the pediatric population with ureteropelvic junction obstruction (UPJO). METHODOLOGY This retrospective study examined the renal cortical thickness in 100 pediatric patients diagnosed with ureteropelvic junction obstruction (UPJO). The study employed a non-probability consecutive sampling technique to select participants. Inclusion criteria encompassed children below five years of age, of both genders, with Pakistani nationality, and availability of both pre-and post-operative ultrasound data. Cases presenting with ureterovesical junction obstruction or vesicoureteral reflux were excluded from the analysis. Data collection involved gathering information on age, gender, and cortical thickness, with renal cortical thickness assessed through ultrasonography. A paired t-test was employed to compare the renal cortical thickness between the preoperative assessment and the 3-month follow-up. RESULTSThe females were 40(40%) and males were 60(60%). The mean age was 33.51±22.91months. The mean cortical thickness before pyeloplasty was 5.23±0.93mm and 8.25 ± 2.34mm after pyeloplasty. The renal cortical thickness in both genders significantly increased to 3mm (p<0.001). The cortical thickness before pyeloplasty was 5.23±0.93mm, and after was 8.25±2.34mm. CONCLUSION Renal cortical thickness can be improved after pyeloplasty in patients with ureteropelvic junction obstruction.

“…During pyeloplasties, DJs are usually used for recovery purposes of the new anastomosis by stenting the reconstructed ureteropelvic junction. Several studies investigated feasibility and outcomes of DJ usage and its variation in length until removal regarding recurrence rates [12][13][14]. However, only 1 previous study investigated the effect of preoperative ureteral rest prior to ureteral reconstruction versus preoperative usage of DJs on perioperative complications and recurrence rates [15].…”

Purpose: This study aimed to evaluate the impact of preoperative double-J stent (DJ) in pyeloplasty patients on perioperative complications, recurrence, and quality of life (QoL). Methods: Pyeloplasties due to ureteropelvic junction obstructions between January 2010 and December 2020 were consecutively identified. A standardized follow-up questionnaire was used. Tabulation was made according to preoperative DJ versus no DJ. Subgroup analyses addressed primary robotic pyeloplasties. Results: Of 95 pyeloplasty patients, 62% received a preoperative DJ. Patients with preoperative DJ exhibited higher rates of Clavien-Dindo (CD) 2 (22 vs. 11%) complications, but not of CD3 (8.5 vs. 8.3%, p = 0.5). After a median follow-up of 61 months, 9 patients exhibited a recurrence, of whom 7 had a preoperative DJ. In QoL assessment, comparable findings were made between patients with and without preoperative DJ. In robotic pyeloplasty patients (n = 73), patients with preoperative DJ (58%, n = 42) experienced higher CD3 complication rates, compared to patients without preoperative DJ (12 vs. 6.5%). Moreover, higher rates of recurrences were observed in preoperative DJ patients (12 vs. 3.2%). Conclusion: In a contemporary pyeloplasty cohort, the midterm success rate was good with 91%. Our findings suggest that preoperative DJ is associated with higher recurrence rates. However, QoL did not differ between patients with and without preoperative DJ.
