Introduction & objectives

Length of hospital stay (LOS) after percutaneous nephrolithotomy (PCNL) is a key quality indicator and is significantly influenced by the method of post-operative renal drainage. We present a series of supine PCNL with ureteric drainage only.

Materials & methods

We recorded peri-operative data of all 'maxi' PCNLS performed in our hospital between January 2015 and July 2018 by single surgeon making the PCNL tract. No percutaneous nephrostomy drainage was used, and either an overnight ureteric catheter or ureteric stent was placed depending on the complexity of procedure.


107 supine PCNLs were performed. The mean patient age was 62 years (27-89) with a mean stone size of 23.2mm (10-66mm). Stone complexity was 25% Guys 1, 37% Guys 2, 21% Guys 3 and 17% Guys 4. 89 patients had a ureteric stent and 18 had a ureteric catheter. The stone free rate was 71% (76/107) with 8 patients requiring a follow-up procedure to clear clinically significant stones. The median length of stay was 1 day (average 2.2 days, range 1-21) with 64% (68/107) going home the day after surgery.


This series shows that avoiding percutaneous renal drainage after supine PCNL can be safe and routinely facilitates discharge on the first post-operative day. The median LOS for PCNL in the U.K is 3 days and percutaneous drainage tubes are used in most patients; we propose this could be significantly and safely reduced by more widespread use of this technique.
