Predictive factors for difficult ureter in primary kidney stone patients before retrograde intrarenal surgery.

Introduction: Ureter may be resistant to insertion of ureteral access sheath (UAS) and/or semi-rigid ureterorenoscope because of the narrow ureter, 'difficult ureter' especially in primary retrograde intrarenal surgery (RIRS) cases. We aimed to delineate the parameters that affect significantly the accessibility of the ipsilateral ureter of the stone-bearing patient side.

Material And Methods: The data of age, gender, body mass index, comorbidities, prior urinary tract infection, prior stone passage, stone burden, stone density, number of stones, stone localization, surgery side, the presence of hydronephrosis and need for double J (DJ) stent due to difficult ureter for all patients were reviewed.

External validation of Ito's nomogram and T.O.HO. scoring system in flexible ureterorenoscopy.

Purpose: This study aims to assess stone-free rates after flexible ureterorenoscopy (fURS) using the T.O.HO.

The fate of clinically insignificant residual fragments following retrograde intrarenal surgery and factors affecting spontaneous passage.

The remaining stone fragments after retrograde intrarenal surgery (RIRS) can lead to stone recurrence/regrowth, or stone-related events (SRE). We aimed to delineate the clinical circumstances that are decisive for spontaneous passage of clinical insignificant residual fragments (CIRF) (primary outcome) and define risk factors for stone recurrence/regrowth and their clinical manifestation (secondary outcome). A total of 115 patients who had CIRF following RIRS were included in this study.

The effect of percussion, diuresis and inversion therapy on RIRS success for lower renal pole stones.

Introduction: Inversion of the patient, forced diuresis after hydration, and mechanical percussion technique was developed for lower renal pole (LRP) stones with extracorporeal shock wave (ESWL). In this study, we aimed to analyze the effect of percussion, diuresis and inversion (PDI) therapy on the success rates of retrograde intrarenal surgery (RIRS) for the LRP stones.

Material And Methods: 114 patients who underwent RIRS for LRP stones <2cm were included in this study.

The importance of periprostatic fat tissue thickness measured by preoperative multiparametric magnetic resonance imaging in upstage prediction after robot-assisted radical prostatectomy.

Purpose: We analyzed the surgical results of patients who were treated and followed up for prostate cancer in our clinic to predict the relationship between periprostatic adipose tissue and patients with and without pathologically upstaged disease.

Materials And Methods: The study included patients who had undergone robot-assisted radical prostatectomy and preoperative multiparametric prostate magnetic resonance imaging between 18 February 2019 and 1 April 2022. The patients were divided into two groups, and the surgical and transrectal ultrasound-guided biopsy pathology results were compared according to tumor grade and distribution in 124 patients who met the selection criteria.

Development of a new scoring system predicting medical expulsive therapy success on 4-10 mm distal ureteral stones: medical expulsive therapy stone score (METSS).

Ureteral stone passage by using medical expulsive therapy (MET) are affected by numerous radiological and clinical parameters. We aimed to construct a scoring system, which would be based on clinical and computed tomography (CT)-derived data, to predict the success of the MET approach. 186 patients presenting to urology clinic or emergency department with unilateral single 4-10 mm distal ureteral stone and who had MET were included.

The Value of Prostate-Specific Antigen Density in Combination with Lesion Diameter for the Accuracy of Prostate Cancer Prediction in Prostate Imaging-Reporting and Data System 3 Prostate Lesions.

Introduction: The aim of the study was to investigate the value of prostate-specific antigen density (PSAD) and lesion diameter (LD) combination in prostate cancer (PCa) detection.

Methods: 181 patients who were detected to have prostate imaging-reporting and data system (PI-RADS) 3 lesions in mpMRI and underwent prostate biopsies were included in the study. Demographic, clinical, and pathological data of all patients were evaluated.

Clinical predictors and significance of adherent periadrenal fat in laparoscopic adrenalectomy.

Background: Adrenalectomy requires the anatomic preparation of the adrenal gland in the fat-rich retroperitoneal space. In the literature, it was shown that the retroperitoneal fat area affects surgical outcomes in laparoscopic adrenalectomy (LA). Besides the quantity of retroperitoneal fat, its qualitative properties play hypothetically a significant role in the safety profile and perioperative parameters of LA.

Efficacy of plasma atherogenic index in predicting malignancy in the presence of Prostate Imaging-Reporting and Data System 3 (PI-RADS 3) prostate lesions.

Purpose: Plasma atherogenic index (PAI) was shown to be positively correlated with the presence of malignity in patients with suspicious findings for renal cell cancer and colon cancer in reported studies. In this study, we aimed to evaluate whether there is an association with the presence of malignity in patients PI-RADS 3 prostate lesions and PAI.

Methods: This retrospective study reviewed the data of 139 patients who underwent transrectal ultrasonography-guided systematic and cognitive fusion prostate biopsy for PI-RADS 3 lesions in multiparametric magnetic resonance imaging.

Cribriform Morphology in Gleason Score 3+4 Moderate-Risk Prostate Cancer: Is it Risk Factor for Biochemical Recurrence?

Objective: Studies have reported that the cribriform morphology observed in prostate biopsy is associated with increased up-staging, upgrading, positive surgical margins and aggressive prognosis after radical prostatectomy. In our study, we aimed to evaluate the relationship between cribriform morphology and biochemical recurrence in patients with moderate-risk localized PCa with a Gleason score of 3+4 (ISUP grade 2) after radical prostatectomy.

Methods: Datas of 177 patients in the moderate-risk group who were evaluated as ISUP grade 2 after radical prostatectomy were retrospectively evaluated.
