Objective: To present a reliable technique for fluoroscopic controlled, large-bore, ureteral stent placement and exchange in transplant kidneys with persistent ureterovesical strictures.
Materials And Methods: We reviewed the medical charts of all patients who underwent kidney transplant with persistent ureterovesical strictures who underwent ureteral stent placement or exchange at our institution between 2005 and 2015 using the new technique. Clinical characteristics and treatment outcomes of the study cohort were analyzed.
Results: Ureteral stent insertion or stent exchange, using this technique, was performed in 32 renal transplant units. Median operating time was 24 minutes (interquartile range, 21-36.75 minutes). The overall success rate of the technique at first attempt was 96.9%. In 1 patient, drainage of the transplanted kidney with a nephrostomy tube was indicated after procedure failure. No other local or systemic complications were encountered, and no stent encrustation was noted in this cohort of patients. Renal function remained stable in all patients during a median follow-up of 59 months (interquartile range, 28-61 months).
Conclusion: Herein, we present in detail a step-by-step technique for the insertion and exchange of large-bore ureteral stents in transplanted kidneys. The technique was shown to be safe, effective, and highly successful.

Several diagnostic and therapeutic endoscopic urological procedures, such as stent placement, ureteroscopy, and bladder stone lithotripsy, can be performed in a hospital, an ambulatory surgery center, in the office with IV sedation, or in the office using only topical anesthesia. The potential benefits of performing procedures in the office setting using topical anesthesia include efficiency and cost reduction. The potential harms are failure to achieve the desired outcome and patient pain.

Ureteral stent must be removed within a certain period, usually performed under the cystoscope. However, cystoscopic operations procedures carry risks such as urethral injury, hemorrhage, and infection. This study aimed to implement a cystoscope-free method for ureteral stent removal during the COVID-19 pandemic to mitigate the complications associated with cystoscopy, reduce the risk of cross-infection, and conserve medical resources and time.

Background: Ureteral stents, such as double-J stents, have become indispensable in urologic procedures but are associated with complications like hematuria and pain. While the advancement of artificial intelligence (AI) technology has led to its increasing application in the health sector, AI has not been used to provide information on potential complications and to facilitate subsequent measures in the event of such complications.
Objective: This study aimed to assess the effectiveness of an AI-based prediction tool in providing patients with information about potential complications from ureteroscopy and ureteric stent placement and indicating the need for early additional therapy.
