We report a case of successful endoscopic stone management in a patient with ectopic ureteric insertion. The patient had a complete duplex collecting system, with the upper moiety ureter inserting ectopically into his prostatic urethra, and an obstructing ureteric stone in the distal portion of the ectopic ureter. This made both characterisation of the patient's anatomy and initial emergency stone management challenging.The case offers several learning points for clinicians who may encounter similar situations. By describing the challenges of managing this patient's presentation, we highlight considerations in imaging interpretation and operative approach that may help the reader manage a similar presentation to their practice. Additionally, we remind the urologist to consider the implications of an ectopic duplex ureter on future procedures, such as transurethral resection of the prostate or radical prostatectomy.
我们报告了一例成功的内镜下结石处理病例，患者为异位输尿管插入。患者存在完全性双肾盂-输尿管系统，上半部分输尿管异位插入其前列腺尿道，异位输尿管的远端有一梗阻性输尿管结石。这使得患者解剖结构的特征描述和最初的紧急结石处理都极具挑战性。该病例为可能遇到类似情况的临床医生提供了几个学习要点。通过描述处理该患者表现的挑战，我们强调了在影像学解释和手术方法方面的注意事项，这可能有助于读者在实践中处理类似的表现。此外，我们提醒泌尿科医生考虑异位双肾盂-输尿管对未来手术（如经尿道前列腺切除术或根治性前列腺切除术）的影响。
