We present the first evaluation of the outcomes of s-PCNL in Malaysia. Our aim was to explore the safety and efficacy of s-PCNL.  Methods: Institutional review board approval was obtained from the National Medical Research Register (NMRR ID-21002225-WLP). We retrospectively reviewed 115 patients with renal pelvis stones who underwent single renal access during s-PCNL between November 2020 and May 2023. Patients who underwent simultaneous ipsilateral or contralateral endourological procedures were included. The data were analysed to determine stone-free rates (SFR), major complication rates, blood transfusion rates, operative times and lengths of hospital stay (LOS).  Results: The SFR was higher for the single middle calyceal renal access (MCA) group than for the lower calyceal renal access (LCA) or upper calyceal renal access (UCA) groups (OR: 1.76; 95% confidence interval [CI]: 0.63, 4.92). In total, 0, 1 and 2 patients had major complications in the UCA, MCA and LCA groups, respectively (P = 0.453). One of the 115 patients (0.9%) needed blood transfusion. Subgroup analysis revealed mean operative times of 76.3 min and 78.6 min for patients who underwent sole s-PCNL (PCNL-only group) and those who had simultaneous ipsilateral and contralateral endourological procedures (PCNL-plus group), respectively (P = 0.786). The overall mean LOS was 2.9 days.  Conclusion: s-PCNL is a safe and effective alternative treatment for renal stones. We would recommend s-PCNL for patients who require an ipsilateral\/contralateral endourological procedure (URS\/RIRS) because it is time-efficient. All renal accesses are safe. Single MCA is recommended for complete stone clearance.<\/jats:p>","DOI":"10.21315\/mjms2024.31.3.9","type":"journal-article","created":{"date-parts":[[2024,7,2]],"date-time":"2024-07-02T12:13:27Z","timestamp":1719922407000},"page":"125-132","source":"Crossref","is-referenced-by-count":0,"title":["First 100 Reported Cases of Supine Percutaneous Nephrolithotomy in Malaysia: An Alternative Effective and Safe Approach to Treat Renal Stones"],"prefix":"10.21315","volume":"31","author":[{"name":"Department of Urology, Sarawak Heart Centre, Sarawak, Malaysia","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ng","family":"Han Kun","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Loo","family":"Chee Hoong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Urology, Sarawak Heart Centre, Sarawak, Malaysia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lim","family":"Meng Shi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Urology, Sarawak Heart Centre, Sarawak, Malaysia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"8963","published-online":{"date-parts":[[2024,6,27]]},"container-title":["Malaysian Journal of Medical Sciences"],"original-title":[],"deposited":{"date-parts":[[2024,7,2]],"date-time":"2024-07-02T12:13:48Z","timestamp":1719922428000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.mjms.usm.my\/MJMS31032024\/MJMS31032024_09.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,6,27]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2024,6,27]]}},"URL":"https:\/\/doi.org\/10.21315\/mjms2024.31.3.9","relation":{},"ISSN":["1394-195X","2180-4303"],"issn-type":[{"value":"1394-195X","type":"print"},{"value":"2180-4303","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,6,27]]}}}
