Median catheterization time was shorter for HoLEP (3 vs 7 days, p <0.001). Transient post-operative incontinence was higher for HoLEP (31% vs 5.3%, p = 0.032). There was no difference in median length of stay (30 hours for HoLEP and 31 hours for STEP; p = 0.108).</p><p><strong>Conclusions: </strong>Both HoLEP and STEP can be safely implemented for the minimally invasive treatment of BPH. Each of the procedures presents some appealing features that can be tailored to different subgroups of patients. HoLEP is appealing for higher surgical risk patients, while STEP allows to effectively manage larger glands even at the beginning of the surgeon's learning curve. As experience with SP robotic surgery matures, it is likely that STEP becomes a competitive alternative to the well-established HoLEP.</p>","PeriodicalId":9744,"journal":{"name":"Central European Journal of Urology","volume":"78 2","pages":"177-180"},"PeriodicalIF":1.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12379826/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144944542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
