RESUMEN
BACKGROUND AND OBJECTIVES: There is no consensus on an ideal abdominal entry in laparoscopic surgery; as such, we aimed to assess the feasibility of the fingertip technique for safe entry and the establishment of pneumoperitoneum in transperitoneal laparoscopic surgery. METHODS: We prospectively assessed 96 consecutive patients who underwent laparoscopic transperitoneal surgery between December 2018 and September 2019. For all patients, pneumoperitoneum was performed using the fingertip technique, which we recently defined. The duration of time for initial entry, the occurrence of gas leakage, and the complications were evaluated. RESULTS: The median duration of initial entry was 90 (75 - 145) seconds. Pneumoperitoneum was established on the first attempt in all patients. Some events were encountered at the time of implementation of the fingertip technique, such as subcutaneous minor bleeding (5.2%) and gas leakage (4.1%). These events were controlled with cauterization and suturing. There was no visceral or major vascular injury in any patient case. CONCLUSIONS: The fingertip technique is a fast, safe, and feasible method for establishing pneumoperitoneum in transperitoneal laparoscopic surgery.

OBJECTIVES: The aim of this study is to evaluate prediction of postoperative ureteral obstruction needing ureteral stent insertion by evaluating the resistive index (RI) values and the grade of hydronephrosis. MATERIAL AND METHODS: A total of 66 adult patients undergoing stentless endoscopic ureteral stone treatment (URS) between January 2018 and January 2019 were included in this prospective study. Preoperative patient and stone characteristics were noted. All patients were evaluated with renal Doppler ultrasonography study to assess degree of hydronephrosis and RI values. A renal Doppler ultrasonography was repeated at postoperative 1st, 3rd and 7th days. Changes in both RI and hydronephrosis levels before and after the procedures were noted. On the postoperative 7th day, patients were divided into two groups including obstructive and non-obstructive cases according to RI values assessed where a RI value of 0.7 was accepted as the cut-off for obstruction. The preoperative and perioperative characteristics of both groups were evaluated in a comparative manner. RESULTS: The mean patient age was 43.6 ± 1.72 years. Significant improvements were noted in RI and grade of hydronephrosis after the operation. The grade of hydronephrosis and RI values were found to improve more significantly on postoperative 3rd day when compared to the postoperative 7th day (p < 0.01 and p < 0.01). A significant correlation was detected between the grade of hydronephrosis (>grade 2) and obstructive RI values (> 0.7) in each postoperative visits (p: 0.001). RI values (> 0.7) at postoperative seventh days were correlated with larger mean stone size, increased ureteral wall thickness, increased diameter of the ureter proximal to the stone, and longer duration of the operation. Preoperative high-grade hydronephrosis indicated obstructive RI values at postoperative seventh day (p = 0.001) Conclusion: Changes in RI values on Doppler sonography and the grade of hydronephrosis may be a guiding parameter in assessing postoperative ureteral obstruction.

OBJECTIVE: The aim of the study was to evaluate the possible effects of calyceal choice for renal puncture under sonographic guidance on the outcomes of percutaneous nephrolithotomy (PNL). MATERIALS AND METHODS: A total of 70 patients for whom ultrasound-guided PNL was planned for 20-30-mm single renal pelvic stones were prospectively allocated to group 1 (n:35) with middle calyx entry or group 2 (n:35) with lower calyx entry. Procedure-related parameters such as duration of operation, stone-free rates, complication rates, and radiation exposure time were analyzed in detail. RESULTS: The mean age of the patients was 45.67 ± 1.50 years and the mean stone size was 316.4 ± 17.95 mm2. There was no significant difference regarding the age, BMI, stone burden, and the grade of hydronephrosis between the groups. Skin to collecting system distance was significantly shorter in the middle calyx entrance (p = 0.021). Total duration of the procedure was again significantly shorter in group 1 cases (74.69 ± 2.94 min) than in group 2 (84.29 ± 4.25 min) (p = 0.003). Regarding the success rates, the postoperative stone-free rate was higher in group 1 (91.4% in group 1, 80.0% in group 2, p = 0.305). Last, there was no statistically significant difference in hemoglobin reduction rates, blood transfusion requirements, and complication rates between the 2 groups. CONCLUSION: Getting access to the renal pelvis through the middle calyx during ultrasonic guided PNL procedure is more advantageous to lower the calyceal approach by reducing both the duration of the PNL procedure with significantly higher stone-free and comparable complication rates.

BACKGROUND: Medical expulsive therapy (MET) is recommended for ureteral stones when there is no indication for interventional treatment. Spontaneous passage (SP) may not always be perceived in patients undergoing MET. We aimed to demonstrate the effects of inflammatory factors on spontaneous ureteral stone passage in patients undergoing MET. METHODS: Our study was conducted between August and November, 2016, in healthy volunteers and patients with a single distal ureteral stone between 5 and 10 mm in diameter and no indications for interventional therapy. Blood and urine samples from all patients and healthy volunteers were tested. The patients were followed up every 2 weeks for 1 month unless emergency situations appeared. Patients with stone-free status at follow-up were concluded to have achieved complete stone passage [SP(+)], and failure [SP(-)] was concluded if the patient had not passed the stone by the end of the study. Blood samples of the patients and the control group were analyzed, recording WBC (white blood cell), CRP (c-reactive protein), SED (sedimentation), MPV (mean platelet volume), NLR (neutrophil-to-lymphocyte ratio), and serum procalcitonin levels. Abnormalities in urine samples were recorded. All patients received diclofenac sodium 75 mg/day, tamsulosin 0.4 mg/day, and at least 3 l/day fluid intake. Patients were followed for a month with kidney, ureter, bladder (KUB) plain films, ultrasonography (USG), and unenhanced abdominal CT scans while undergoing MET. Comparative statistical analyses were performed between the SP(+) and SP(-) groups. RESULTS: The procalcitonin levels of the SP(-) group were significantly higher (207 ± 145.1 pg/ml) than in the SP(+) group (132.7 ± 28.1 pg/ml) (p = 0.000). The leucocyturia rate of the SP(-) group was significantly higher than in the SP(+) group (p = 0.004). Based on the ROC curve analysis, 160 pg/ml (86.7% sensitivity, 70.8% specificity, p < 0.001; AUC: 0.788 95% CI (0.658-0.917) was identified as the optimal cut-off value for procalcitonin. In logistic regression analysis, a significant efficacy of procalcitonin and leucocyturia was observed in the univariate analysis on spontaneous passage. In the multivariate analysis, significant independent activity was observed with procalcitonin. (p < 0.05). CONCLUSION: Our findings suggest that high procalcitonin levels and the presence of leucocyturia have a strong negative effect on SP of ureteral stones between 5 and 10 mm in diameter. This relationship can be explained by stone impaction, possibly caused by increased mucosal inflammation.

Recent studies have suggested that a relationship could exist between 25-hydroxyvitamin D [25(OH)D] deficiency and erectile dysfunction (ED). The present study evaluated the relationship between 25(OH)D levels and ED in male patients with type 2 diabetes mellitus (DM). The study included 98 patients with type 2 DM aged between 18-80 years. The International Index of Erectile Function (IIEF-5) Questionnaire was administered. The patients were divided into three groups according to IIEF-5 scoring: IIEF-5 score between 5-10, severe ED; IIEF-5 score between 11-20, moderate ED; IIEF-5 score between 21-25, no ED. Biochemical parameters, 25(OH)D and hormonal analysis tests were obtained in all patients. All parameters were compared between these three groups. Of 98 patients included in the study, 32 had severe ED, 45 had moderate ED and 21 had no ED. The mean age was 55.12 ± 9.39 years and the mean 25(OH)D level was 13.69 ± 8.15 ng/ml. When the three groups were compared, 25(OH)D levels were significantly lower in patients with the IIEF-5 score between 5-10 (p = 0.020). There was a moderate positive relationship between IIEF-5 score and 25(OH)D level (r = 0.21, p = 0.038). The patients with severe ED have considerably lower 25(OH)D levels.
