Introduction: Strengthening The Reporting Of Cohort Studies in Surgery (STROCSS) guidelines were developed in 2017 in order to improve the reporting quality of observational studies in surgery and updated in 2019. In order to maintain relevance and continue upholding good reporting quality among observational studies in surgery, we aimed to update STROCSS 2019 guidelines., Methods: A STROCSS 2021 steering group was formed to come up with proposals to update STROCSS 2019 guidelines. An expert panel of researchers assessed these proposals and judged whether they should become part of STROCSS 2021 guidelines or not, through a Delphi consensus exercise., Results: 42 people (89%) completed the DELPHI survey and hence participated in the development of STROCSS 2021 guidelines. All items received a score between 7 and 9 by greater than 70% of the participants, indicating a high level of agreement among the DELPHI group members with the proposed changes to all the items., Conclusion: We present updated STROCSS 2021 guidelines to ensure ongoing good reporting quality among observational studies in surgery., (Copyright © 2021 The Authors.

Simple renal cysts are among the most common cystic lesions of the kidney. Renal cysts most often remain asymptomatic, but rarely these cysts may become huge in size and result in significant symptoms. Giant renal cysts present a technical challenge in terms of surgical management. Although laparoscopic procedures have been performed successfully at experienced centres, intraperitoneal marsupialization via open approach may be a feasible option at less experienced centres. We report a case of a young female with a giant (24 × 18 cm) renal cyst of Bosniak type-II variety. De-roofing and intraperitoneal marsupialization of the cyst was performed. At the 1-year follow-up, she was asymptomatic, with no residual cyst.

Aim: To assess sustained virological response (SVR) rates in a predominantly hepatitis C virus (HCV) genotype 4 infected population., Methods: Between 2003-2007, 240 patients who were treated for chronic hepatitis C infection at our center were included. Epidemiological data, viral genotypes, and treatment outcomes were evaluated in all treated patients. Patients with chronic renal failure, previous non-responders, and those who relapsed after previous treatment were excluded from the study. Among all patients, 57% were treated with PEG-interferon (IFN) alpha-2a and 43% patients were treated with PEG-IFN alpha-2b; both groups received a standard dose of ribavirin., Results: 89.6% of patients completed the treatment with an overall SVR rate of 58%. The SVR rate was 54% in genotype 1, 44% in genotype 2, 73% in genotype 3, and 59% in genotype 4 patients. There was no statistical difference in the SVR rate between patients treated with PEG-IFN alpha-2a and PEG-IFN alpha-2b (61.5% vs 53%). Patients younger than 40 years had higher SVR rates than older patients (75% vs 51%, P = 0.001). SVR was also statistically significantly higher when the HCV RNA load (pretreatment) was below 800.000 (64% vs 50%, P = 0.023), in patients with a body mass index (BMI) less than 28 (65% vs 49%, P = 0.01), and in patients who completed the treatment duration (64% vs 8%, P

Objective: It was the aim of this study to assess the efficacy and safety of combined forced hydration and diuresis with limited inversion during shock wave lithotripsy (SWL) by comparing this treatment modality with conventional SWL for lower calyceal nephrolithiasis., Patients and Methods: In this prospective, non-randomized study, we included 100 patients with lower calyceal calculi 0.05). Complications were minimal and not statistically significant., Conclusions: Forced diuresis and inversion therapy is very well tolerated; however, the stone-free rate was not significantly improved., (Copyright (c) 2009 S.
