Article Synopsis
  • Surgeons face high stress during urological procedures, impacting their health and well-being, and heart rate variability (HRV) serves as a valid stress indicator.
  • This study analyzed HRV during surgical interventions, comparing senior and junior surgeons' stress responses at key surgery moments: incision, closure, and adverse events.
  • Results showed senior surgeons had greater stress indicators, such as higher heart rate decreases and lower HRV, compared to juniors, suggesting they experience more physiological changes during surgery.

Article Synopsis
  • Urosepsis is a common complication following flexible ureterorenoscopy (F-URS), occurring in up to 4.3% of cases and accounting for significant healthcare costs.
  • A study involving 486 F-URS procedures at eleven French centers evaluated clinical factors that increase the risk of urosepsis, identifying key risk indicators.
  • Results indicated that a type IV calculus (carbapatite or struvite), along with factors like coronary insufficiency and larger stone size, significantly increase the risk of post-operative urosepsis, emphasizing the need for enhanced monitoring in these cases.

Prevalence of kidney stones is increasing worldwide, flexible ureterorenoscopy (f-URS) is the most common surgical treatment. Postoperative urinary tract infection (PUTI) is the primary complication. Some risk factors are classically associated with PUTI, especially preoperative positive urinalysis (POPU).

Objective: Several studies have reported blood transfusion were associated with a decrease of survival after oncological surgery. For kidney cancer, the effect of blood transfusion is still debated. The objective of this study was to determine the effect of blood transfusion after oncological nephrectomy on overall, specific and recurrence-free survival in a retrospective cohort of localized or locally advanced kidney cancer.

Goal: The goal was to evaluate the results of sacral neuromodulation (SNM) in non-neurological vesical emptying disorders.

Patients And Methods: From February 2010 to October 2017, 28 patients presenting voiding symptoms or a non-obstructive chronic urine retention without neurological cause have been operated for an SNM (test phase). The test was positive in case of decreased number of proper intermittent self-catheterization (SC) or post-voiding residual urine (PVR) of at least 50 %.

Article Synopsis
  • The study aimed to assess four different predictive scores for stone-free rates (SFR) following flexible ureterorenoscopy (f-URS) using holmium-YAG laser to treat kidney stones.
  • A retrospective analysis of 800 f-URS procedures was conducted, with various scores (S.T.O.N.E, RUSS, S-ReSC, and Ito's score) calculated by a single surgeon.
  • The results showed an overall SFR of 74.1%, with Ito's score being the most sensitive, although all score performances were lower than previously reported in earlier studies.

Objective: The objective of this study was to analyze the effects of obesity on postoperative complications and patient and graft survival after kidney transplantation.

Methods: We retrospectively included 506 patients who received a kidney transplant in our center during eleven years. Obesity was defined by a body mass index ≥ 30 kg/m based on World Health Organization criteria.

Aim: Evaluate the concordance between the renal lesions biopsy's histology and the final histology of the surgical specimen according to histological subtype, and search for predictive factors of non-concordance.

Material: We performed a monocentric retrospective study that included 156 patients suffering from a renal tumor that benefited a lesion biopsy before surgical treatment. Sensibility and specificity of the renal lesion's biopsy for histological diagnostic of the different renal tumors where calculated.

Purpose: The aim of this study was to evaluate the efficacy and tolerance of renal stone fragmentation by flexible ureterorenoscopy (URS), compared to percutaneous nephrolithotomy (PCNL).

Material And Methods: Patients treated between 1998 and 2010 by URS and PCNL for intrarenal stone were reviewed. Patients' and stones' characteristics were analyzed.

Objective: To analyze results (stone-free rate [SFR]) and complications after flexible ureterorenoscopy (f-URS) for renal or lumbar ureteral lithiasis in patients with a previous ureteral stenting (US).

Patients And Methods: We conducted a single-center retrospective study, including all f-URS procedures achieved in our department, between January 2004 and December 2010, for renal or lumbar ureteral urinary lithiasis. In total, 497 procedures were performed: 316 procedures in patients with a ureteral stent placed before the surgery for renal colic, sepsis, or renal failure (group 1) and 181 procedures in patients without US (group 2).

Primary tumors of the epididymis are rare. Adenomatoid tumors are benign, usually found within the wall of fallopian tubes or beneath the uterine serosa. They are most frequently diagnosed as benign tumors of the epididymis and represent 30% of paratesticular tumors.

Objective: To determine whether obesity is associated with adverse pathologic characteristics, positive surgical margins and the biochemical recurrence free survival (bRFS) after primary treatment with radical prostatectomy (RP).

Patients And Methods: Medical charts of patients managed with RP between 1999 and 2011 for localized prostate cancer (PCa) were retrospectively reviewed. Population study was split into two groups according to the body mass index (BMI): non obese (BMI< 30 kg/m(2)) and obese (BMI ≥ 30 kg/m(2)).

Objective: To analyze results and morbidity after flexible ureterorenoscopy (fURS) in patients with a body mass index (BMI)>30 kg/m² and to compare with results obtained in a large cohort of non-obese patients.

Methods: We conducted a retrospective monocenter study including all fURS for urinary lithiasis performed in our institution between January 2004 and December 2010. During the study period, 497 procedures were performed.

Objectives: To analyze the impact of the existence of Gleason grade 5 on the adverse pathology and biochemical recurrence-free survival of patients.

Patients: Three hundred and seventy-two prostatectomies were performed between 1999 and 2011 in our institution for localised prostate adenocarcinoma. We examined the existence of grade 5 of the specimen to determine the reliability of prostate biopsies in the diagnosis of grade 5 and the association of grade 5 with other histoprognostic factors.

Background And Purpose: Flexible ureterorenoscopy (f-URS) for lower pole stones (LPS) compared with other renal locations can be challenging because of anatomic and technical considerations. We aimed to compare the stone-free rate (SFR) and surgical complication rate with f-URS for LPS vs other renal locations.

Patients And Methods: We performed a retrospective, single-center study including 371 f-URS for renal stone retrieval performed in our institution between January 2004 and December 2010.

The Lithiasis Committee of the French Association of Urology (CLAFU) aimed to update the current knowledge about urolithiasis. This update will be divided into four parts: 1) general considerations; 2) the management of ureteral stones; 3) the management of kidney stones; 4) metabolic assessment and medical treatment of urolithiasis. Recent technicals advances helped the urologists to improve stones management: new extracorporeal shockwave lithotripsy (ESWL) devices, new flexible ureterorenoscopes, development of laser fragmentation.

Introduction: The therapeutic approach of prostate cancer depends mainly on pathological criteria obtained through prostate biopsy. The low accuracy of prostate biopsy for Gleason grade determination is well known but its accuracy for bilateral or multifocal tumor has not been evaluated. The goal of this study was to assess the concordance between prostate biopsy and whole prostate specimen obtained after radical prostatectomy especially for bilateral and/or multifocal tumor.
