Urinary pH Measurement after Renal Obstruction. Can it Be Used as a Marker for Recovery of Renal Function?

Abstract

We identified 42 cases (17 supine and 25 prone), all with an ASA grade of 1-3. Operating times were on average 107.5 min (supine) and 101.8 min (prone). Average hospital stay was 4.5 and 5.1 nights respectively. There were three post operative complications in the supine cohort and five in the prone. Seven supine patients had ureteric stents inserted compared to two prone. Overall, 15/17 (88%) supine and 22/25 (88%) prone cases had complete clearance at fluoroscopic and nephroscopic (rigid and flexible) assessment. Conclusion:In this single centre, single surgeon audit, we have demonstrated equivalence in most of the parameters studied since introducing a significant modification of our PCNL technique. In our opinion, the advantages of the supine technique make it preferable going forward, while we intend to maintain the capability to perform either approach.
