We conducted this systematic review to compare surgical outcomes and postoperative complications of M-PCNL vs. S-PCNL in staghorn calculi treatment. A systematic search of the literature was performed on PubMed, Cochrane Library, ProQuest, Scopus, ClinicalTrials.gov, and Google Scholar according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (PRISMA Statement). Five randomized controlled trial (RCT) and 5 cohort studies were included. Risk of bias assessment was evaluated using Cochrane risk of bias (RoB) 2 and Cochrane RoB in Nonrandomized Studies - of Interventions (ROBINS-I). Ten studies involving 1733 staghorn calculi patients met the inclusion criteria. The stone-free rate (SFR) was comparable (odds ratio (OR) 1.13, 95% CI: 0.90-1.43, P = .28) compared to S-PCNL. Pooled analysis showed that M-PCNL resulted in a significantly lower shorter operative time (mean differences (MD) 14.06, 95% CI: 6.09-22.03, P < .001), lower blood transfusion (OR 0.46, 95% CI: 0.29-0.72, P < .001), and lower hemoglobin drop (MD !0.37, 95% CI: !0.72 to !0.03, P = .03) compared to S-PCNL.

This study was conducted in children who were diagnosed accidentally and investigated for VUR and UTI.</p><p><strong>Methods: </strong>This longitudinal retrospective study was conducted in children with a diagnosis of a small kidney accidentally discovered by ultrasonography and referred to Children's Hospital in Babol, Iran, between 2012-2022. They were investigated by DMSA (dimercapto succinic acid) renoscintigraphy scans. Vesicoureteral reflux was diagnosed by voiding Ccystourethrography (VCUG) or radionuclide cystography (RNC). All children were followed for at least for 1 year with urine culture and urinalysis every 1-2 months for detection of UTI. Significance was set at P less than .05.</p><p><strong>Results: </strong>The mean age of the children with small-size kidneys was 5.52 ± 3.70 years, and 58.1% were boys. Out of the 86 children, 28 (32.6%) were found to have VUR, with approximately 71.4% of them being boys. Breaking down by gender, 40% of boys and 28.6% of girls with small-sized kidneys had VUR. Among the children with and without VUR, 42.9% and 10.3% experienced UTIs, respectively (P=.74). The predominant causative microorganism for UTIs was Escherichia coli (55.6%), with Klebsiella (22.4%) and Enterobacter (22.4%) accounting for the remaining cases.</p><p><strong>Conclusion: </strong>Accidental diagnoses of small-size kidneys in children revealed a notable presence of VUR, with a higher prevalence in boys. This suggests that VUR may constitute a significant etiological factor in the development of small-size kidneys. We recommend that these children must be evaluated for VUR.</p>","PeriodicalId":101337,"journal":{"name":"Urology research & practice","volume":"50 4","pages":"230-233"},"PeriodicalIF":0.0,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11883671/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143054742","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}
