RESUMO
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.
