Objective: This study presents the surgical, oncological, and functional outcomes of the first 93 robotic radical prostatectomy (RARP) procedures performed in Erzurum, Turkey. These procedures were performed by a single surgeon who had completed the European Association of Urology Robotic Urology Section (ERUS) RARP curriculum in an ERUS-certified training center in Ankara. Material and methods: The study present the results of 93 RARP procedures performed by a single surgeon. The surgeon performing the operations completed an ERUS training program structured for RARP by two robotic surgeons holding ERUS training certificates in an ERUS-approved academic robotic surgery training center in Ankara.The RARP cases performed by the surgeon after completion of the training between April 2016 and August 2018 were retrospectively evaluated. Results: The mean patient age was 63.62±7.04 years, and the mean preoperative serum prostate-specific antigen level was 8.34±4.96 ng/mL. Preoperatively, 82 and 4 patients had prostate biop­sy Gleason scores of 3+3 and 4+3, respectively. Bilateral neurovascular bundle (NVB) sparing, unilateral NVB-sparing, and non-NVB-sparing surgery were performed in 21, 13, and 59 cases, respectively. The mean prostate weight was 85.34±47.57 g. Posterior rhabdosphincter reconstruction was performed in 60 (64.5%) cases. Mean console time, intraoperative blood loss, duration of hospital stay, and urethral catheter removal time were 170.49±36.50 min, 100.70±34.08 cc, 6.84±2.28 days, and 7.40±3.11 days, respectively. During the perioperative period (0–30 days), five minor (prolonged drain output, n=3; rectocele, n=1; gout arthritis, n=1) and six major (inguinal hernia, n=1; incisional hernia, n=2; anastomotic urinary leakage, n=2; myocardial infarction, n=1) complications were identified. No complication was detected during postoperative days 31–90. Postoperative pathological stages included pT2a, pT2b, and pT2c disease in 77 (82.8%), 9 (9.7%), and 7 (7.5%) patients, respectively. The positive surgical margin (SM) rate was 10.7% (n=10), including patients with pT2a (n=6) and pT2c (n=2) diseases. Eleven (11.8%) patients underwent pelvic lymph node (LN) dissection. The mean LN yield was 16.45±4.29. The mean length of follow-up was 11.17±8.01 months. Biochemical recurrence was observed in two patients, one of whom received maximal androgen blockage (MAB), and the other one received pelvic radiotherapy+MAB. All the patients with at least one-year follow-up (n=48, 51.6%) were fully continent (0 pads/day). Of the 40 (43%) patients with no preoperative erectile dysfunction (ED) and with at least three-month follow-up, 18 (45%) had no ED, with or without any additional medication including phosphodiesterase-5 (PDE5) inhibitors. Conclusion: RARP is a safe minimally invasive procedure with acceptable morbidity, excellent operative, pathological and oncological outcomes, and satisfactory functional results. The ERUS RARP curriculum provides effective and sufficient training. Cite this article as: Bedir F, Keske M, Demirdöğen ŞO, Kocatürk H, Koç E, Canda AE, et al.

Objective: To compare microscopic inguinal (MIV) and subinguinal varicocelectomy (MSV) surgeries with respect to efficacy and safety. Material and methods: Patients who underwent varicocelectomy between January 2002 and January 2018 were evaluated retrospectively and prospectively. The patients who underwent varicocelectomy until December 2015 were analyzed retrospectively and the cases after January 2016 were analyzed prospectively. In our study, the married infertile male cases were compared on the basis of operation duration, number of ligated veins, number of preserved veins, postoperative pain score (visual analogue scale: VAS), patient satisfaction, surgeon satisfaction, changes in sperm parameters, testicular consistency, pregnancy rates, and complications, such as hydrocele, testicular atrophy, and recurrence of varicocele. Surgical success rates were compared by semen analysis between unmarried infertile male cases because pregnancy rates cannot be tested. The patients were recalled for control examinations every 3 months for 1 year and tested the above-mentioned parameters. Statistical Package for the Social Sciences Version 20 Windows Software was used for data analysis and comparison between the two groups. Results: The study included a total of 136 adult patients. Mean age of the patients was 28.14 (20–41) years. MSV and MIV were performed in 62 (45.6%) and 74 (54.4%) patients, respectively. No statistically significant difference was detected between the two groups in terms of admission duration, semen parameters within the 1-year follow-up process, hormonal changes, and complication rates. Operation duration was significantly longer in the MSV group. It was determined that a fewer number of veins were ligated, and a fewer number of veins needed to be ligated in the MIV group. The analysis of all the patients revealed that pain scores at 4 and 24 hours postoperatively were significantly statistically lower in the MSV group. Conclusion: MIV and MSV are distinct, efficient, and safe surgical techniques with specific advantages and disadvantages. Their efficacy and safety rates are similar.

Crimean–Congo hemorrhagic fever (CCHF) is an acute infectious disease that affects multiple organ systems and is characterized by extensive ecchymosis, internal hemorrhage, and hepatic dysfunction. The reported case fatality rate varies between 8% and 80%. It is frequently transmitted by Hyalomma ticks, which are endemic in the Northeast Anatolia region of Turkey in spring and summer. Our patient presented from an endemic area with fever, malaise, joint pain, and scrotal pain following a tick bite, and real-time PCR analysis of venous blood was positive for CCHF. Based on Doppler ultrasound performed because of the patient’s scrotal pain, he was diagnosed as having epididymo-orchitis, which was considered secondary to CCHF after ruling out other etiologies and resolved with scrotal elevation and anti-inflammatory treatment. Being a very rare complication, this report aimed to document this case of CCHF-associated epididymo-orchitis in the literature.

Objective: The aim of this study was to retrospectively examine the patients who underwent surgical treatment for vesicovaginal fistula (VVF) repair in our clinic, to evaluate our surgical preferences, success, and treatment results, to compare these with the literature, and firstly to reveal the necessity of cystostomy and its effect on treatment success. Material and methods: Between 1985 and 2018, a retrospective evaluation was performed on the records of 102 patients who underwent surgical treatment for VVF repair. All cases underwent a detailed physical examination and had their routine laboratory tests and imaging methods. In obese patients, a Foley catheter was moved into the bladder through the fistula tract, then inflated in order to push the vagina and bladder wall upwards. A transurethral catheter was used in all cases, and cystostomy was used in 58 (56.9%). Results: The most common cause was prior hysterectomy for benign diseases in 35 (34.31%) cases. Among a total of 102 cases with for VVF, 95 (93.1%) were primary, 5 (4.9%) secondary, and 2 (1.9%) tertiary. The transvesical and O’Connor approaches (transabdominal) were performed in 61 (59.8%) and 41 (40.2%) cases, respectively. Transvaginal approach was not used in any of the cases. Cystostomy was applied in 58 (56.9%) of cases and not applied in 44 (43.1%). Conclusion: Complete excision of the fistula tract and sealing of the layers separately using the water-tight technique are extremely crucial factors to increase the success rate of VVF repair. In cases where good transurethral drainage is ensured, cystostomy is unnecessary and may increase the risk of infection.

Introduction: To determine whether a combination of the long acting local anesthetic, bupivacaine, and lidocaine is better than lidocaine alone in the long-term pain control, which is a short-acting anesthetic. Materials and Methods: In group 1, periprostatic nerve block was applied to both neurovascular areas with 2% lidocaine (5 ml) in an isotonic solution (5 ml). In group 2, the combination of 2% lidocaine (5 ml) and 5mg/ml bupivacaine (5 ml) was used for the PPNB. Results: In the first 30 minutes the mean VAS scores of groups 1 and 2 were 2.1 ± 0.2 and 1.2 ± 0.1, respectively (p = 0.002). VAS scores of group II determined at 1, 2, 4, 6, and 8 hours after the biopsy were significantly lower since it was (p < 0.05). Conclusion: While periprostatic nerve block for late phase pain control, applying a combination of a long-acting local anesthetic, such as bupivacaine, is effective in terms of pain control and patient comfort.
