Objective: To evaluate the impact of ureteral stent insertion following semirigid ureterorenoscopy (URS) in patients with perirenal fat stranding (PFS) due to ureteral stones. Material and methods: Data of 600 patients who underwent URS were analyzed retrospectively. Seventy-two patients detected to have PFS accompanying ureteral stone were included. Patients who did not undergo double J (DJ) stent insertion following semirigid URS were classified as Group I (n: 52), while those who underwent stent insertion were classified as Group II (n: 20). Side distribution; localization of the stones, stone size, presence of fever, urinary tract infection (UTIs) and urosepsis rates were compared in the two groups. Results: The average age of the patients was 44.4 (20-71) years. Male/female ratio and side of the stone location showed similar distribution in both groups (p > 0.05). Fever occurred in 23 cases (44.2%) in Group I and in 15 cases (75%) in Group II (p = 0.038). UTIs occurred in 15 cases (28.9%) in Group I and in 12 cases (60%) in Group II (p = 0.03). Urosepsis presented in 3 (5.8%) and 5 (25%) of the patients in Group I and II, respectively (p = 0.033). Conclusions: According to our results, ureteral DJ stent insertion following URS in patients with PFS due to ureteral stone caused an increase on postoperative infection related complications.

Aortic stiffness increases in patients with erectile dysfunction (ED) but it is not known whether aortic stiffness affects the degree of ED. In the present study, we aimed to determine whether there is any relationship between aortic stiffness and the severity of ED. Patients with ED were divided into 3 groups according to the International Index of Erectile Function (IIEF) scores. Mild ED was named as group 1, moderate ED as group 2 and severe ED as group 3. The values of fasting blood glucose (FBG), serum lipid values, total testosterone (T. tes), and free testosterone (F tes) were recorded. Aortic stiffness was determined by pulse wave velocity (PWV) and augmentation index (AIX) measurements. The mean or median values of the laboratory parameters among the groups were similar (p > .05). No statistical difference was found between the groups in terms of AIX value (p = .386). Mean PWV values were calculated as 7.26, 8.30 and 8.78 in group 1, group 2 and group 3 respectively. PWV values were significantly different between groups (p < .0001). PWV values were found to be increased with increasing severity of erectile dysfunction.

Objective: Urinoma is a rare entity and mainly occurs due to acute obstruction such as ureteral stone. We aimed to demonstrate factors associated with urinoma accompanied by ureteral calculi. Material and methods: Data of 550 patients who were diagnosed with ureteral stone by computed tomography (CT) were analyzed retrospectively. In 20 patients perirenal urinoma was associated with ureteral calculi (group I), whereas in other 530 patients no urinoma was detected (group II). Gender, age, size, side and localization of the stone, hydronephrosis, fever, sepsis, urinary tract infections (UTIs), hematuria, serum creatinine, blood urea nitrogen (BUN), white blood cell (WBC), C-reactive protein (CRP), presence of diabetes mellitus (DM), hypertension (HT) and cronic kidney disease (CKD) of the two groups were compared. Results: The average age of the patients were 46.2 (20-71) and 44.9 (10-82) years in group I and group II, respectively (p > 0.05). According to our results leukocytosis, microscopic and macroscopic hematuria, UTIs, increase of serum creatinine, BUN and CRP, diagnosis of DM and HT were significantly associated with urinoma (p < 0.05). In addition, patients with distal ureteral stones are more prone to urinoma (p = 0.001). An interesting finding of the study was that the stone size in group I (median 5 mm [range 3-8]) was significantly smaller than in group II (9.3 mm [4-25]; p = 0.001). Conclusions: Small stone size, distal localisation of the stone in ureter, leukocytosis, hematuria, UTIs, increase of serum creatinine, BUN and CRP, presence of DM and HT are associated with perirenal urinoma.

The relationship between the results of penile duplex Doppler ultrasound (PDDU) and response to vardenafil was investigated in patients diagnosed with erectile dysfunction (ED). Data from 148 patients with ED were analyzed retrospectively. Patients who did not respond to therapy were classified in to Group I (n = 32), those who responded partially were classified into Group II (n = 40), and complete responders were classified into Group III (n = 76). Age, comorbidities, and vascular and penile pathologies were compared among the three groups. While diabetes mellitus (DM) and dyslipidemia positivity adversely affected the response to treatment, the presence of hypertension (HT), Peyronie’s disease and priapism increased the therapeutic response to the treatment (p < 0.05). Arterial insufficiency was present in 20 (30.3%), 25 (37.9%) and 21 (31.8%) of the patients in Group I, Group II and Group III, respectively (p = 0.001). Venous insufficiency was observed in three (14.3%) patients in Group I and in eight (85.7%) patients in Group III (p = 0.001). Arterial/venous insufficiency was seen in 9 (30%), 14 (46.7%) and 7 (23.3%) of the patients in Group I, Group II and Group III, respectively (p = 0.001). The response rate to treatment was highest in normal patients according to PDDU, followed by patients with venous insufficiency. In addition, it was found that DM decreased the response to treatment, whereas the response increased in cases with HT, priapism and Peyronie’s disease.
