ABSTRACT
PURPOSE:
The aims of this study were to analyze the clinical outcomes of treating duplex system ureteroceles with early endoscopic puncture decompression and to identify the risk factors related to outcomes to help guide future work. MATERIALS ANDMETHODS:
We retrospectively reviewed the clinical records of patients with ureteroceles with duplex kidney that were treated with early endoscopic puncture decompression. Charts were reviewed for demographics, preoperative imaging, surgical indications, and follow-up data. Recurrent febrile urinary tract infections (fUTIs), de novo vesicoureteral reflux (VUR), persistent high-grade VUR, unrelieved hydroureteronephrosis, and the need for further intervention were considered unfavorable outcomes. Gender, age at surgery, BMI, antenatal diagnosis, fUTIs, bladder outlet obstruction (BOO), type of ureterocele, ipsilateral VUR diagnosed before surgery, simultaneously upper-pole moiety (UM) and lower-pole moiety (LM) obstruction, the width of ureter affiliated to UM, and maximum diameter of ureterocele were all considered potential risk factors. A binary logistic regression model was used to identify the risk factors of unfavorable outcomes.RESULTS:
A total of 36 patients with ureteroceles related to duplex kidney underwent endoscopic holmium laser puncture from 2015 to 2023 at our institution. After a median follow-up of 21.6 months, unfavorable outcomes developed in 17 patients (47.2%). Three patients underwent ipsilateral common-sheath ureter reimplantation and one patient underwent laparoscopic ipsilateral upper to lower ureteroureterostomy combined with recipient ureter reimplantation. Three patients underwent laparoscopic upper-pole nephrectomy. Fifteen patients suffered from recurrent UTIs were treated with oral antibiotics and eight of them were diagnosed de novo VUR according to voiding cystourethrography (VCUG). In univariate analysis, patients with simultaneously UM and LM obstruction (P = 0.003), fUTIs before surgery (P = 0.044), and ectopic ureterocele (P = 0.031) were more likely to have unfavorable outcomes. Binary logistic regression analysis showed that ectopic ureterocele (OR = 10.793, 95% CI 1.248-93.312, P = 0.031) and simultaneously UM and LM obstruction (OR = 8.304, 95% CI 1.311-52.589, P = 0.025) were identified as independent factors for unfavorable outcomes.CONCLUSIONS:
Our study suggested that early endoscopic puncture decompression is not a preferred but an available treatment option to release BOO or to cure refractory UTIs. It was easier to fail if the ureterocele was ectopic or simultaneously UM and LM obstruction existed. Gender, age at surgery, BMI, antenatal diagnosis, fUTIs, bladder outlet obstruction (BOO), ipsilateral VUR diagnosed before surgery, the width of ureter affiliated to UM, and maximum diameter of ureterocele were not significantly related to the success rate of early endoscopic punctures.Palavras-chave
