AI Article Synopsis
- - The study compared the effectiveness of surgical cryoablation (SCA) and percutaneous cryoablation (PCA) for treating renal tumors by analyzing the outcomes of 194 patients over a follow-up period.
- - Both treatment methods yielded similar rates of overall survival (OS), cancer-specific survival (CSS), and recurrence-free survival (RFS), with five-year rates showing slight variations but no significant differences between the two approaches.
- - PCA resulted in a much shorter hospital stay (0.7 days) compared to SCA (3.2 days), indicating it may be a more convenient option for patients while still offering effective treatment.
Article Abstract
Purpose: To compare outcomes between patients undergoing surgical and percutaneous cryoablation for treatment of renal masses and identify prognostic variables that determine survival.
Patients And Methods: We retrospectively evaluated the medical records of 194 patients who underwent cryoablation for renal tumors between 1997 and 2008 at a single large center. Patient demographics, tumor characteristics, perioperative data, and follow-up details were recorded. Univariate and multivariate Cox proportional hazards analysis was performed to identify predictors of overall (OS), cancer-specific (CSS), and recurrence-free survival (RFS).
Results: Cryoablation was performed percutaneously (PCA) in 141 patients for 154 tumors, while 53 patients were treated surgically (SCA) using an open or laparoscopic approach for 54 tumors. Mean follow-up was 44.5 months in SCA and 36.1 months in PCA. PCA had a shorter duration of hospital stay (0.7 days vs 3.2 days, P<0.0001). The rate of residual (P=0.38) and recurrent disease (P=0.18) was not significantly different between the two groups. Five-year OS, CSS, and RFS were 78.81%, 100%, and 85.23% for SCA, and 77.71%, 98%, and 95.56% for PCA, respectively; the type of approach was not predictive of OS, CSS, and RFS.
Conclusions: SCA and PCA both provide adequate oncologic control for renal masses. Duration of hospital stay was lower in patients undergoing PCA.

The rising incidence of osteoporotic vertebral compression fractures (OVCF) has increased the demand for precise treatments like robot-assisted percutaneous vertebroplasty (PVP), especially for conditions like Kümmell's disease that require high surgical accuracy. However, the traditional tracer fixation method has certain limitations. This study aimed to compare the safety and clinical efficacy of a modified tracer fixation technique with the traditional fixation method in robot-assisted percutaneous vertebroplasty (PVP) for Kümmell's disease.

Studies in literature discussed the drawbacks of the ureteral access sheath use in flexible ureteroscopy and in the same time mentioned the benefits of ureteral access sheath in decreasing the incidence of urosepsis and better stone free rate. In the current study we aim to compare between percutaneous nephrostomy tube (PCN) insertion before flexible ureteroscopy and conventional ureteral access sheath (UAS) flexible ureteroscopy in terms of safety, efficacy and perioperative outcomes. In all, 100 Patients aged 20 to 67 years with upper ureteric stones and mild hydronephrosis or renal pelvic stones less than 20 mm with mild hydronephrosis were randomized into 2 groups; patients undergoing PCN insertion before flexible ureteroscopy, and patients undergoing the conventional UAS flexible ureteroscopy.

Percutaneous tumor ablation has become a widely accepted and used treatment option for both soft and hard tissue malignancies. The current standard-of-care techniques for performing these minimally invasive procedures require providers to navigate a needle to their intended target using two-dimensional (2D) US or CT to obtain complete local response. These traditional image-guidance systems require operators to mentally transpose what is visualized on a 2D screen into the inherent three-dimensional (3D) context of human anatomy.

Introduction: Percutaneous needle fasciotomy (PNF) is a non-invasive treatment option for finger flexion contractures caused by Dupuytren's disease. Variations in PNF techniques include the use of corticosteroid injection. In the presented randomised controlled trial, we compare the efficacy of PNF +/- corticosteroid injection in terms of reducing the recurrence rate.
