Rethinking Time-to-Exchange: Outcomes of Nephrostomy Tube Placement in Pregnancy

2022 Recommendations of the AFU Lithiasis Committee: Management of symptomatic urinary stones

The acute situation, caused by an obstructive stone, is defined by a renal colic that may be uncomplicated, complicated, or at risk in specific conditions. Its management may be medical or require interventional treatment by extracorporeal shockwave lithotripsy, endoscopic removal, or ureteroscopy. METHODOLOGY: These recommendations were developed using two methods, the Clinical Practice Recommendations (CPR) and the ADAPTE method, in function of whether the question was considered in the European Association of Urology (EAU) recommendations (https://uroweb.org/guidelines/urolithiasis) [EAU Guidelines on urolithiasis. 2022] and whether they could be adapted to the French context.

New clinic workflow improves compliance for routine PCN exchanges

PURPOSE

To examine the effect of a clinic workflow intervention on follow-up for routine ercutaneous nephrostomy tube (PCN) exchanges.

METHODS

An intervention consisting of automated electronic tracking for all PCN placements and exchanges followed by phone call reminders to schedule a follow-up exchange 60 days post-procedure was introduced on March 19, 2019. All PCN exchanges performed from March 19, 2018 to September 18, 2019 were identified through a local electronic database search to assess the impact of intervention as a quality improvement project. Basic demographic information and procedure details were collected. Routine follow-up at our institution is recommended every 90 days. The exchange rates within 90 days were compared between groups using a Chi-squared test.

RESULTS

A total of 160 PCN placements or exchanges were performed pre-intervention and 69 PCN exchanges were performed post-intervention. Pre-intervention, 75/160 (46.3%) were exchanged within 90 days compared to 47/69 (68.1%) exchanged within 90 days post-intervention. The remainder had delayed follow-up due to loss to follow-up or scheduling delays. Post-intervention, there was a significantly improved rate of compliance for PCN exchanges within the recommended 90 days at our institution (p-value = 0.002).

CONCLUSION

Automated tracking and phone call follow-up at 60 days post-procedure is a simple and effective intervention that can improve compliance for routine PCN exchanges and reduce the number of patients that are lost to follow-up.
