RESUMO
INTRODUCTION: Shared decision making (SDM) in surgical specialties was demonstrated to diminish decisional regret, decisional anxiety and decisional conflict. Urolithiasis guidelines do not explicit patient preference to choose treatment. The aim of this review article was to perform a systematic evaluation of published evidence regarding SDM in urinary stone treatment. METHODS: A systematic review in accordance PRISMA checklist was conducted using the MEDLINE (PubMed) database. Inclusion criteria were studies that evaluated stone treatment preferences. Reviews, editorials, case reports and video abstracts were excluded. ROBUST checklist was used to assess quality of the studies. RESULTS: 188 articles were obtained. After applying the predefined selection criteria, seven articles were included for final analysis. Six out of seven studies were questionnaires that propose clinical scenarios and treatment alternatives. The last study was a patient preference trial. A general trend among included studies showed a patient preference towards the least invasive option (SWL over URS). The main reasons to choose one treatment over the other were stone-free rates, risk of complications and invasiveness. DISCUSSION: This review provides an overview of the patients' preferences towards stone treatment in small- and medium-sized stones. There was a clear preference towards the least invasive management strategy. The main reason was less invasiveness. This is opposed to the global trends of performing more ureteroscopies and less SWL. Physicians played a pivotal role in counselling patients. SDM should be encouraged and improved. The main limitation of this study is the characteristics of the included studies.

ABSTRACT Introduction: The management of urolithiasis ectopic pelvic kidneys (EPK) can be challenging because of the aberrant anatomy (1-4). We demonstrate the step-by-step technique of the laparoscopic approach for treating urolithiasis in EPK. Patients and methods: Three men with EPK (2 left, 1 right) underwent laparoscopic pyelolithotomy through a transperitoneal approach. After establishing the pneumoperitoneum, the parietal peritoneum was opened at the parietal colic sulcus and the bowel displaced medially. The kidney was identified in the retroperitoneum and the renal pelvis exposed after removal of the perirenal adipose tissue. The renal pelvis was opened, and the stones were identified and retrieved with forceps in 2 cases and with a flexible nephroscope in 1 case. The renal pelvis was closed with a 3/0 running barbed suture. A DJ stent was placed in all patients. Results: For the first time, a laparoscopic technique for treating stones in the ectopic kidney is demonstrated in detail. Mean patient age was 52.6 years (44-58). The mean stone size was 22.3 mm (20-24 mm). Stones were in the renal pelvis in 2 cases and in the inferior calyx in 1 case. Mean operative time was 146 minutes (135-155 min). Mean estimated blood loss was 116 ml (60-140 ml). No complications were observed. The mean hospital stay was 3 days. The DJ stents were removed after 3 weeks. All patients were stone free at the postoperative CT scan with a mean follow-up of 3.3 months (1-6 months). Conclusions: Laparoscopic pyelolithotomy can be an effective and reproducible minimally invasive technique for treating urolithiasis in EPK.

INTRODUCTION: One of the main limitations of Ho:YAG lithotripsy is represented by its advancement speed. The need for faster lithotripsy has led to the introduction of high-power laser equipment. This general trend in increasing Ho:YAG lithotripsy power has certain points that deserve to be considered and analyzed. The objective is to carry out a narrative review on intrarenal temperature and pressure during ureteroscopy. METHODS: A literature search using PUBMED database from inception to December 2021 was performed. The analysis involved a narrative synthesis. RESULTS: Using more power in the laser correlates with an increase in temperature that can be harmful to the kidney. This potential risk can be overcome by increasing either the irrigation inflow or outflow. Increasing irrigant flow can lead to high intrarenal temperature (IRP). The factors that allow the reduction of intrarenal pressure are a low irrigation flow, the use of a ureteral access sheath of adequate diameter according to the equipment used, and the occupation of the working channel by the laser or basket. CONCLUSION: To maintain a safe temperature profile, it has been proposed to use chilled irrigation fluid, intermittent laser activation or to increase irrigation flow. This last recommendation can lead to increased IRP, which can be overcome by using a UAS. Another option is to use low power laser configurations in order to avoid temperature increases and not require high irrigation flows.
