    To compare the outcomes of flexible ureterorenoscopy (F-URS) with extracorporeal shock wave lithotripsy (ESWL) for the treatment of upper or mid calyx kidney stones of 10 to 20 mm. A total of 174 patients with radioopaque solitary upper or mid calyx stones who underwent ESWL or F-URS with holmium: YAG laser were enrolled in this study. Each group treated with ESWL and F-URS for upper or mid calyx kidney stones were retrospectively compared in terms of retreatment and stone free rates, and complications. 87\% (n = 94) of patients who underwent ESWL therapy was stone free at the end of 3rd month. This rate was 92\% (n = 61) for patients of F-URS group (p = 0.270 p > 0.05). Retreatment was required in 12.9\% of patients (n = 14) who underwent ESWL and these patients were referred to F-URS procedure after 3rd month radiologic investigations. The retreatment rate of cases who were operated with F-URS was 7.5\% (n = 5) (p = 0.270 p > 0.05). Ureteral perforation (Clavien grade 3B) was occured in 3 patients (4.5\%) who underwent F-URS. Fever (Clavien grade 1) was noted in 7 and 5 patients from ESWL and F-URS group, respectively (6.4\% vs 7.5\%) (p = 0.78 p > 0.05). F-URS and ESWL have similar outcomes for the treatment of upper or mid calyx renal stones of 10-20 mm. ESWL has the superiority of minimal invasiveness and avoiding of general anethesia. F-URS should be kept as the second teratment alternative for patients with upper or mid caliceal stones of 10-20 mm and reserved for cases with failure in ESWL.

    Abdominal or Transrectal Ultrasonographic Prostate Volume and Cystoscopic Prostatic Urethral Length Measurements to Determine the Surgical Technique for Prostatectomy in Patients with Benign Prostate Hyperplasia
    (GALENOS YAYINCILIK, 2016-01-01) Demir, Aslan; Karadag, Mert Ali; Cecen, Kursat; Turkeri, Levent
    Objective We aimed to determine the most suitable technique for prostate volume (PV) measurement to decide for the most appropriate surgical approach - endoscopic or open - by establishing the relationship between imaging techniques and the resected tissue weight (RTW). Materials and Methods Sixty men aged 49-95 years with lower urinary tract symptoms, who were scheduled for transurethral resection, were enrolled. The relationship of RTW with PV determined by preoperative abdominal ultrasonography as well as transrectal ultrasonography (TRUS) performed at the table just before surgery, and prostatic urethral length (PUL) measured at the time of cystoscopy was analyzed. Two groups were established with respect to PV, (less than or equal to 75 cc and greater than 75 cc, respectively), and according to PUL (less than or equal to 2.5 cm and longer than 2.5 cm, respectively). Statistical analyses were performed between the groups to identify the best correlation between resected tissue weight and pre-surgical volume determination methods. Results The strongest correlation between RTW and prostatic volume measurements was established for the TRUS measurements (r=0.79
