![]() However, late recurrences arise therefore, patients should be subject to long-term follow-up. ![]() Most recurrences occurred within the first year. Minimally invasive treatment is a worthwhile alternative in strictures due to previous radiation and/or surgical treatment of malignancies. 3/6 patients were successfully re-dilated. All 6 recurrences occurred within 36 months, 4 within the first 12 months. We identified 32/43 (75%) balloon dilatations, 10/43 (23%) catheter dilatations and 1/43 (2%) laser incision. Preoperative decompression was required in 30/43 (70%). The largest proportion of strictures occurred following surgery combined with radiotherapy 8/43 (19%). ![]() ResultsĤ3 patients were eligible for retrospective final analysis. Successful outcome was defined as an asymptomatic, completely catheter free patient, with stable renal function. All patients but one were treated with antegrade, retrograde balloon or catheter dilatations. We excluded 16 patients from final analysis due to failed access or loss to follow-up. Over a 5-year period, 2007–2012, we analyzed the data of 59 consecutive patients undergoing minimally invasive treatment for symptomatic ureteric strictures. Our study aimed to retrospectively assess the long-term efficacy of minimally invasive treatment in benign and malignant ureteric strictures. There are no existing guidelines on which techniques to use in the treatment of different stricture types and a paucity of data regarding long-term results. Minimally invasive treatment using endoscopic dilatation or laser incision is the standard practice. Ureteric strictures are well-documented complications related to surgery or radiation therapy.
