We aimed to compare the outcomes of mini-percutaneous nephrolithotomy (mPNL) and standard PNL techniques in the treatment of renal stones ≥ 2 cm. The study was designed as a randomized prospective study between January 2016 and April 2017. The patients with a kidney stone ≥ 2 cm were included in the study. Patients who had uncorrectable bleeding diathesis, abnormal renal anatomy, skeletal tract abnormalities, pregnant patients and pediatric patients (< 18 years old) were excluded from the study. The remaining patients were randomly divided into two groups as standard PNL and mPNL. For both group, demographic data, stone characteristics, operative data and postoperative data were recorded prospectively. The study included 160 consecutive patients who had kidney stone ≥ 2 cm. Of these, patients who met the exclusion criteria and patients who had missing data were excluded from the study. Remaining 97 patients were randomly divided into two groups as mPNL (n: 46) and standard PNL (n: 51). The mean age was 46.9 ± 13.7 and 47.4 ± 13.9 years for mPNL group and sPNL group, respectively. According to Clavien–Dindo classification, no statistical difference was detected between the groups in terms of complication rates (p 0.31). However, the rates of hemoglobin drop and transfusion rates were significantly in favour of mPNL (p 0.012 and p 0.018, respectively). Nephrostomy time and hospitalization time was found to be significantly shorter in mPNL group (p 0.017 and p 0.01, respectively). The success rate in the mPCNL group was higher than standard PNL group, however, this difference was statistically insignificant (76.5 vs 71.7%, p 0.59). Both mPNL and standard PNL are safe and effective treatment techniques for the treatment of kidney stones of ≥ 2 cm. Although there was no significant difference in success rates of both techniques; nephrostomy time, hospitalization time, bleeding and transfusion rates were in favour of mPNL.

Dapoxetine hydrochloride is a selective serotonin reuptake inhibitor and the first drug approved for the on-demand treatment of premature ejaculation (PE). Our objective in this study was to characterize the efficacy of on-demand dapoxetine (30 and 60 mg) and daily paroxetine (20 mg) usage in treating PE. We conducted a 1 month study involving a total of 150 patients. Patients were divided into three groups of 50. Group 1 were treated with on-demand dapoxetine (30 mg), Group 2 with on-demand dapoxetine (60 mg) and Group 3 with daily paroxetine (20 mg). Our outcome measurement was increased from baseline intravaginal ejaculatory latency time (IELT) after treatment. The IELT increased from baseline to posttreatment by 117%, 117% and 170% in the paroxetine group (P < 0.01), 30 mg dapoxetine group (P < 0.01) and 60 mg dapoxetine group (P < 0.01), respectively. The increase from baseline IELT were similar for the 30 mg dapoxetine and paroxetine groups (P > 0.05), while the 60 mg dapoxetine group had a larger posttreatment IELT increase compared with the 30 mg dapoxetine (P < 0.05) and paroxetine (P < 0.01) groups. Dapoxetine (60 mg) 1-3 h before planned intercourse is a very effective treatment modality for PE. However, an on-demand dose of 30 mg dapoxetine is no more effective than the currently prescribed paroxetine treatment.

Abstract Objective: The aim of this study is to describe a novel transobturator midurethral sling surgery technique by using rectus abdominis fascia. Material and methods: A 54-year-old woman complaining of urinary leakage during effort was diagnosed as pure stress urinary incontinence after detailed questioning, pelvic examination, uroflowmetry and measurement of residual urine volume. She was anxious about complications related to synthetic meshes. However, she was not interested in relatively morbid surgeries such as colposuspension and pubovaginal sling. Autologous transobturator midurethral sling was discussed with the patient. The patient approved the surgery and the surgery was planned. A 5 cm rectus fascia was harvested via suprapubic incision and non-absorbable stay sutures were placed on its’ both edges. Anterior vaginal incision together with paravaginal dissection was performed, as in classical transobturator sling surgery. Groin puncture and blind dissection of adipose tissue was performed. C-shaped trocars were inserted, and advanced through groin punctures and brought up to midurethral incision by finger guidance. Stay sutures were transported via C-shaped trocars to the groin puncture in both sides. Graft was positioned on the midurethral part without any tension and stay sutures were tied to create a tissue bridge on obturator membrane. Incisions were closed and vaginal tampon was placed. Patient was discharged at the first postoperative day. Results: At postoperative third and sixth months, patient was totally dry and did not have any voiding complaints. Small abdominal and vaginal incisions were clean, as well. Conclusion: Autologous transobturator midurethral sling surgery is a safe, effective and feasible surgical option for stress urinary incontinence in the era which mesh-related concerns are rising. Studies with larger volume and long-term follow up periods are needed. Cite this article as: Çubuk A, Erbin A, Savun M, Ayrancı A, Üçpınar B, Yanaral F, et al.

Abstract Objective: The aim of study was to compare the efficiency and safety of standard percutaneous nephrolithotomy (sPNL) and miniaturized percutaneous nephrolithotomy (mPNL) in lower calyx and/or pelvic stones smaller than three centimeters. Material and methods: From October 2010 to August 2015, 108 mPNL and 176 sPNL procedures were performed for renal stones smaller than three cm and located in the lower calyx and/or renal pelvis. All patients were evaluated preoperatively with intravenous pyelography and/or computed tomography. Intraoperative parameters, post-operative results and complications were recorded. Postoperative success was defined as complete stone clearance and/or clinically insignificant residual fragments at 3rd month. Results: Preoperative characteristics were similar between sPNL and mPNL groups except previous renal stone operation history and gender. The mean operation time was significantly shorter in the sPNL group (p<0.001). The mean hemoglobin drop was significantly less in the mPNL group (p=0.001), we found a 1.27±1.4 and 0.5±1.3 decrease in mean hemoglobin levels (mg/dL) in the sPNL and mPNL groups, respectively. Transfusion rate was 1.9% in mPNL and 5.6% in sPNL groups, and the difference was statistically significant (p=0.048). Only one patient in the sPNL group needed angiography and embolization. Postoperative JJ stent insertion rate was significantly higher in the mPNL group (p=0.03). Conclusion: Both sPNL and mPNL are safe and effective surgical procedures for lower calyx and/or pelvis stones smaller than 3 cm. However, use of smaller caliber instruments was associated with a lesser hemoglobin drop and need for transfusion.

Abstract Objective: In obese patients, the management of renal calculi presents a number of challenges for urologists. In this study, we aimed to evaluate the efficacy and safety of percutaneous nephrolithotomy (PNL) procedure in obese and morbidly obese patients. Material and methods: We retrospectively reviewed the medical files of 2360 patients treated with PNL between March 2002 and April 2013. The patients were stratified into four groups according to the World Health Organization (WHO) classification of body mass index (BMI): <25 kg/m2 (average), 25-29.9 kg/m2 (overweight), 30-39.9 kg/m2 (obese), and >40 kg/m2 (morbidly obese). Patients under 18 years of age and those with a body mass index under 18 kg/m2 were excluded from the study. Intra-,and postoperative outcomes of PNL were compared between groups. Results: A total of 2102 patients with a mean age of 43±13.62 years were enrolled in the study. The mean stone size, mean number of stones, staghorn stone rate and history of previous shock wave lithotripsy were similar in all groups. The overall stone-free rate was 82 percent. The mean operation time was longer in the morbidly obese group but it was not significantly different from that in the other groups. No differences were observed in hospital stay, complication or stone-free rate among four study groups. Conclusion: Percutaneous nephrolithotomy is a safe and effective treatment for renal stone disease. Body mass index does not affect the success or complication rate in PNL.

Tranexamic acid, once a randomly used antifibrinolytic agent, has been in standard protocols for many specific surgeries. Studies are still needed to standardize the dose and route of tranexamic acid administration, examine its possible contributions in urological surgery, and establish a protocol for its use. To contribute to this goal, we designed a prospective, randomized, double-blind study on 75 patients with 1 control and 2 study groups (n = 25) who underwent percutaneous nephrolithotomy. Group Tranexamic acid received 10 mg/kg intravenous tranexamic acid preoperatively. And Group Irrigation received the same amount in the initial irrigation fluid. Primarily, we observed the total amount of blood transfusion and the changes in hemoglobin and hematocrit values during 2 postoperative days. Distinctively, we intraoperatively monitored hemoglobin continuously as a saturation hemoglobin value to assess the timing of the effect of tranexamic acid. Secondarily, we questioned surgical visual clarity with a standard visual score to reveal its contribution to surgical practicality, operative time, and residual fragment quantity. Our results revealed a significant difference in the reduction of hemoglobin and hematocrit change and blood transfusion in both tranexamic acid groups concerning control, especially on the second day (p = 0.003, p = 0.002, p = 0.001). Likewise, surgical visual scores were significantly better in both tranexamic acid groups (p = 0.018). In conclusion, intravenous or local administration of tranexamic acid at a dose of 10 mg/kg will be sufficient to maintain perioperative stability in hemoglobin values, use fewer blood products and provide a better visual advantage for the surgeon intraoperatively.The trial registration number is NCT05947435, and the date of registration is 07/07/2023, retrospectively registered.

Abstract Objective: To present the first 24 laparoscopic adrenalectomies performed in our clinic because of an adrenal mass. Material and methods: The medical files of 24 patients who underwent laparoscopic adrenalectomy between December 2008 and March 2013 at Haseki Teaching and Research Hospital were analyzed retrospectively. The demographic characteristics of the patients were recorded. Lateral transperitoneal laparoscopic adrenalectomy was performed in all patients. The operation time was defined as the interval between the first incision of the skin and closure of the skin. Intraoperative complications, estimated blood loss and hospital stays of the patients were evaluated. Final pathologies were recorded. Results: The mean age of the patients was 44.2±8.58 years (range: 29-66 years). Nine patients were female and 15 were male. A total of 24 masses were identified in the right (n=11), and left (n=13) adrenal glands masses were identified., Eighteen patients (75%) had no symptoms, and the masses were identified incidentally. The mean operation time was 144±46.1 minutes (range: 90-320 minutes), and the mean blood loss was 74±12.3 mL (range: 50-130 mL). None of the patients required a blood transfusion. In one patient, liver injury was identified intraoperatively due to traction. The mean duration of hospitalization was 2.9±1.1 days (range: 2-5 days). Adrenocortical adenoma and pheochromocytoma were the most common pathologies. Conclusion: Laparoscopic adrenalectomy is a safe and effective method for the treatment of adrenal masses with low complication rates.

OBJECTIVES: The aim of this study is to evaluate the short-term outcomes of our modified autologous transobturator tape(aTOT) technique with rectus abdominis muscle fascial graft for the treatment of female stress urinary incontinence (SUI). MATERIAL AND METHODS: The data of 22 patients who underwent modified aTOT were recorded. Perioperative data regardingoperative time, complications and postoperative visual analogue scores were noted. Patients were assessed 18 monthsafter surgery. The primary endpoints of this study were the improvements in the International Consultation on IncontinenceQuestionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) subscores, one-hour pad test and cough stress testrates as an objective cure as well as the improvements in the PGI-I and ICIQ-FLUTS quality of life scores as a subjective cure. RESULTS: Mean age and the mean follow-up period were 51.7 ± 9.8 years and 20.1 ± 0.9 months, respectively. Urethralhypermobility and a positive cough stress test were detected in all the patients. Mean operative time was 43.8 ± 8.1 min.and the overall complication rate was 9%. Mean VAS scores at postoperative 24 hours were 2.6 ± 1.2. At the postoperativeeighteenth month, no patient had a positive cough test and mean PGI-I score was 2 while two patients had moderateurinary incontinence according to the pad test. Pad test results, ICIQ subscores of voiding QoL, incontinence, incontinenceQoL, total score and total QoL score at baseline and eighteen months after surgery were 76.9 ± 19.9, 9.6 ± 4.1, 15.5 ± 4.0,39.5 ± 7.9, 27.9 ± 6.6, 68.4 ± 13.8 and 7.1 ± 2, 10.1 ± 2.4, 6.6 ± 2.1, 13.4 ± 4.5, 20.4 ± 4.8, 39.7 ± 9.2 respectively (p = 0.001,p = 0.004, p = 0.001, p = 0.001, p = 0.001, and p = 0.001, respectively) CONCLUSIONS: Modified aTOT is an effective and safe method with low morbidity for SUI treatment in short term.

The miniaturized percutaneous nephrolithotomy (mPNL) can be performed by using a very wide range of different access sheaths (14-22 Fr).It has been well known that tract size is one of the main parameters affecting the complication rates in PNL. We aimed to compare 21 Fr with 16.5 Fr mPNL tract sizes in adult patients. From May 2013 to April 2018, 604 patients with kidney stone underwent mPNL in our department. The study was designed as retrospective and match-pair analysis was the preferred method for the formation of groups.  The 21 Fr mPNL cases were matched with 16.5 Fr mPNL cases at a 1:1 ratio, according to the patients' age, gender, body mass index, American Society of Anesthesiologists (ASA) score, stone characteristics (stone size, opacity and localization) and hydronephrosis. Patients with solitary kidney, renal anomalies, musculoskeletal abnormalities, and pediatric patients (< 18 years old) were excluded from the study. Both groups (21 Fr and 16.5 Fr) were compared in terms of demographics, stone characteristics, operative data and post-operative outcomes. A total of 260 patients were included in the study (130; 21 Fr mPNL group and 130; 16.5 Fr mPNL group). The operation time was significantly shorter in 21 Fr group (21 Fr; 85.2±37.5, 16.5 Fr; 101.7±37.7 minutes, p: 0.001). Complete stone clearance rates were 76.9% and 62.3% in 21 Fr and 16.5 Fr mPNL, respectively (p: 0.01). There was no significant difference between the groups in terms of overall operative and post-operative complications. However, in subgroups analysis, post-operative fever was higher in 16,5 Fr mPNL (4 patients in 16.5 Fr, no patients in 21 Fr group, p: 0.044); steinstrasse, renal colic and post-operative JJ stent requirement rates were higher in 21 Fr mPNL procedure (p: 0.018, p: 0.031 and p: 0.046, respectively). The hospitalization time was significantly higher in 21 Fr (p: 0.01). Although 21 Fr mPNL procedure has advantages such as better success rates and shorter operation time, some post-operative complications (steinstrasse, renal colic, post-operative JJ stent requirement) are against of 21 Fr mPNL when compared with 16.5 Fr mPNL procedure. Further randomized prospective studies with larger patient volume are needed to confirm these results.
