Evaluation of the optimal duration for retrograde intrarenal stone surgery to prevent postoperative complications.

OBJECTIVE: To evaluate retrograde intrarenal surgery (RIRS) outcomes and to determine the effect of operative time on complications of RIRS. METHODS: Patients undergoing RIRS for renal stones were evaluated. These patients were divided into two groups according to the operation time (Group 1<60 minutes and Group 2>60 minutes). Peroperative outcomes such as fluoroscopy time, stone-free rates, complications and duration of hospitalization were compared. RESULTS: Group 1 consisted of 264 patients and Group 2 consisted of 297 patients. SFR rates, duration of hospitalization, and postoperative urinary tract infection rates were similar in both groups. Fluoroscopy time was 7.8±7.3 (0-49) sec in group 1 and 13.1±9.8 (0-81) sec in group 2. Complications according to modified Clavien-Dindo classification system (MCDCS) were 13 and 32 patients (Grade 1), 31 and 63 patients (Grade 2), 1 and 1 patient (Grade 3) in group 1 and 2, respectively. There was statistical difference between the two groups in terms of duration of fluoroscopy time and the MCDCS. Although duration of hospitalization and UTI rates were higher in group 2, no statistical significance was observed among groups. CONCLUSION: Limiting the operation time to 60 minutes in RIRS seems to be important in reducing postoperative complications.

Ultra-mini Percutaneous Hepatolithotomy in Patients With Large and Multiple Hepatolithiasis.

BACKGROUND: In this study, we applied the ultra-mini percutaneous hepatolithotomy (UM-PHL) technique on hepatolithiasis patients with multiple and large stones on which other minimally invasive methods failed, and our aim was to report its results, sharing in series for the first time. MATERIALS AND METHODS: Preoperative and postoperative data, laboratory parameters, radiologic findings, and preoperative and postoperative details were recorded for a total of 14 patients for whom the UM-PHL technique was applied between April 2017 and December 2019. As all patients had multiple stones and extreme stone load and had bile duct surgery, they did not have a normal anatomy. All patients were radiologically confirmed to have had preprocedural magnetic retrograde cholangiopancreatography. RESULTS: Operation duration of the patients was 137.6±44.9 minutes, while intraoperative blood loss was 69.2±24.9 mL, drainage catheter removal time was 2.85±0.86 days, and the hospitalization time was 4.28±2.55 days. Intraoperative balloon dilation was applied to enlarge the stricture area in 5 patients (35.7%). On the basis of the Clavien-Dindo classification, grade 2 complication was observed in 2 patients (14.2%) due to postoperative cholangitis. Patients were followed up for an average of 15 months, and nonsymptomatic radiologic stone recurrence was detected in the 12th month control of 1 patient (7.1%). CONCLUSION: The UM-PHL technique is a successful method that facilitates stone clearance by providing minimal dilatation through percutaneous intervention and by using instruments with small diameter, and it can safely be applied with its low complication level, low recurrence ratio, and short hospitalization time.

Efficiency of intracavernosal alprostadil and oral clomiphene citrate combination treatment in penile vasculogenic erectile dysfunction patients accompanied by late-onset hypogonadism.

In this study, the efficiency of intracavernosal alprostadil + oral clomiphene citrate (CC) treatment in late-onset hypogonadism (LOH) accompanied by penile vasculogenic erectile dysfunction (PVED) in patients irresponsive to phosphodiesterase type 5 inhibitor treatment was evaluated. A total of 31 patients with concurrent PVED and LOH were included in the study. The patients were given intracavernosal alprostadil (10-20 µg) and oral CC (50 mg) every day for 12 weeks. Before and after treatment, a 15-question International Index of Erectile Function (IIEF-15) questionnaire, Erection Hardness Score (EHS), Sexual Encounter Profile (SEP)2 and SEP3 levels were analysed, and follicle stimulating hormone (FSH), luteinising hormone (LH), total testosterone and prostate-specific antigen (PSA) levels were measured. In all, 41.9% of patients had pure arterial deficiency, 19.3% had pure venous deficiency, and 38.7% had arterial + venous (mixed) deficiency. A significant increase was detected in total testosterone, FSH, LH and PSA values after treatment when compared to values before treatment (p < .001, p < .001, p < .001 and p = .034 respectively). A significant recovery was observed in IIEF-15 subscores, EHS and SEP2-SEP3 results. In PVED patients accompanied by LOH, intracavernosal alprostadil and oral CC combination is an efficient, low cost, safely applicable and tolerable treatment.
