RESUMO
OBJECTIVE: We aimed to evaluate the results of laparoscopic pyeloplasty with concomitant pyelolithotomy and compare results with a cohort of patients undergoing laparoscopic pyeloplasty without pyelolithotomy. MATERIALS AND METHODS: We retrospectively reviewed records of 43 patients undergoing transperitoneal laparoscopic Anderson-Hynes dismembered pyeloplasty between December 2012 and July 2018 at our department. Eighteen patients (42%) underwent laparoscopic pyeloplasty with concomitant pyelolithotomy. The results of patients with renal stones were compared with 25 matched patients undergoing laparoscopic pyeloplasty without concomitant renal stones. Demographic data, operative and stone parameters were compared between the groups. RESULTS: The groups were similar regarding to demographic characteristics. All operations were completed laparoscopically with no conversions to open surgery. In 3 cases without renal stones and 15 cases with renal stones, transposition of the ureter due to crossing vessels was performed. The mean stone size was 13±5.24 mm, and the median number of stones was 1 (1-18). The success of laparoscopic pyeloplasty with and without pyelolithotomy was 93.3% and 92.9%, respectively, as confirmed by negative diuretic renogram at postoperative 3rd months. Overall stone-free rate after laparoscopic pyelolithotomy was 93.3%. Mean operative time was 222.6765.71 minutes vs. 219.11±75.63 minutes for the pyeloplasty with concomitant pyelolithotomy vs. pyeloplasty, respectively (p=0.88). CONCLUSIONS: Laparoscopic pyeloplasty with concomitant pyelolithotomy is a safe and effective intervention with associated good cosmetic results and high stone-free rates without significant increase in operative time or complications.

OBJECTIVES: Paraoxonase-1 (PON1) is a high-density lipoprotein-associated enzyme implicated in the pathogenesis of atherosclerosis by protecting lipoproteins against peroxidation. PON1 has two genetic polymorphisms both due to amino acid substitution, one involving glutamine and arginine at position 192 and the other leucine and methionine at position 55. Recent reports suggest that nephrolithiasis and atherosclerosis share a number of risk factors. Our study aimed to compare the effects of PON1 192, PON1 55 polymorphisms, and PON1 activity in patients with urolithiasis and controls. MATERIALS AND METHODS: PON1's arylesterase/paraoxonase activities and phenotype were determined in 158 stone forming cases (Group 1) and 138 non-stone forming controls (Group 2). The PON1 192 and PON1 55 polymorphisms were studied by polymerase chain reaction/restriction fragment length polymorphism. RESULTS: Paraoxonase activity was significantly lower in Group 1 than Group 2 (112 ± 31.8 vs. 208 ± 53.1 IU/L) (p < 0.001). The PON1 L55M polymorphism was significantly higher in Group 1. The "M" allele coding for PON1 was higher in Group 1 (p < 0.001). PON1 192 RR homozygotes had significantly higher PON1 activity than QR and QQ genotypes among all the patients (p < 0.001). CONCLUSION: The results of our study demonstrate that the PON1 55 gene "M" allele is associated with renal stone disease. Individuals possessing the "M" allele have a higher incidence of urolithiasis. The results of this study provide genetic evidence that the PON1 gene may play a role in stone formation. PON1 genotype determination may provide a tool to identify individuals who are at risk of urolithiasis.

To compare the outcomes of flexible ureterorenoscopy (F-URS) and mini-percutaneous nephrolithotomy (mini-PNL) in the treatment of lower calyceal stones smaller than 2 cm. Patients who underwent F-URS and mini-PNL for the treatment of lower calyceal stones smaller than 2 cm between March 2009 and December 2014 were retrospectively evaluated. Ninety-four patients were divided into two groups by treatment modality: F-URS (Group 1: 63 patients) and mini-PNL (Group 2: 31 patients). All patients were preoperatively diagnosed with intravenous pyelography or computed tomography. Success rates for F-URS and mini-PNL at postoperative first month were 85.7% and 90.3%, respectively. Operation time, fluoroscopy time, and hospitalization time for F-URS and mini-PNL patients were 44.40 min, 2.9 min, 22.4 h, and 91.9 min, 6.4 min, and 63.8 h, respectively. All three parameters were significantly shorter among the F-URS group (p < 0.001). Postoperative hemoglobin drop was significantly lower in F-URS group compared to mini-PNL group (0.39 mg/dL vs. 1.15 mg/dL, p = 0.001). A comparison of complications according to the Clavien classification demonstrated significant differences between the groups (p = 0.001). More patients in the F-URS groups require antibiotics due to urinary tract infection, and more patients in the mini-PNL group required ureteral double J catheter insertion under general anesthesia. Although both F-URS and mini-PNL have similar success rates for the treatment of lower calyceal stones, F-URS appears to be more favorable due to shorter fluoroscopy and hospitalization times; and lower hemoglobin drops. Multicenter and studies using higher patient volumes are needed to confirm these findings.

OBJECTIVE: The aim of the study was to compare the efficacy of the laser lithotripter with the ultrasonic lithotripter in mini percutaneous nephrolithotomy (miniperc). MATERIAL AND METHODS: From June 2013 to January 2014; medical records of 77 consecutive patients who underwent miniperc operation were retrospectively evaluated. Ultrasonic lithotripter was used in 22 patients (Group 1), while laser was used in 55 patients. In the laser group, 22 patients were randomly selected who had same characteristics compared to group 1 (Group 2). Success rate, total operative time, complications according to modified Clavien classification, fluoroscopy time, haemoglobin drop, hospital stays and cost analysis were assessed. Success rates were evaluated on the second postoperative day and after the first month. RESULTS: Total operative time (p = 0.635) and fluoroscopy time (p = 0.248) were not significantly different between the two groups. In the laser group, the success rate (81.8%) was notably more than in the ultrasonic lithotripter group (68.2%) but there was no statistically significance (p = 0.296). Ten reusable ultrasonic probe were used for 22 patients, due to thinness and sensitiveness of the probe. Conversely, one single laser fiber (550 micron) was used for 22 patients. When the cost analysis of lithotripsy was considered, the cost per case was 190 dollar in group 1 and 124 dollar in group 2. (p = 0.154) Complication rate, hospital stay and haemoglobin drop were similar in both groups. CONCLUSION: Laser lithotripsy seems to be more cost effective than ultrasonic lithotripsy for miniperc but larger number of patients are required to confirm this estimation.

AIM: The aim of this study was to evaluate cure rate and mid-term results of tension-free vaginal tape for recurrent stress urinary incontinence after failed transobturator tape surgery. MATERIAL AND METHODS: Between January 2006 and December 2011, 42 women were enrolled in this study. Patient characteristics and operating parameters were recorded, and any complications were noted. All patients were followed up for at least 24 months after the second surgery. The Incontinence Impact Questionnaire and the Urinary Distress Inventory were used to identify satisfaction level. RESULTS: The mean age of the patients was 49.07 ± 8.6 years, and median period between transobturator surgery and the tension-free vaginal tape procedure was 12.8 (range 9.2-17.8) months. The cure rate was 83.3% and 76.2% at the first- and second-year follow-up visits, respectively. Intraoperative complications were transient and slight. Bladder injury in five patients and subcutaneous hematoma above the pubis in two patients were the most serious complications, but they were managed conservatively. We found the scores of the Incontinence Impact Questionnaire and Urinary Distress Inventory to be significantly lower at follow-up, compared to the preoperative assessment. De novo urgency was the most common complaint at follow-up and occurred in 11.9% of the women. CONCLUSIONS: We suggest that tension-free vaginal tape is a feasible surgical option for recurrent stress urinary incontinence. Further studies with larger patient numbers and longer follow-up periods are needed to support this finding.

AIM OF THE STUDY: To investigate success of endoscopic lithotripsy for bladder stone following stress urinary incontinance surgery and contraception surgery. MATERIALS AND METHODS: Charts of patients admitted in two centers between January 2006 and March 2013 were retrospectively reviewed and seven women were enrolled in our study. Patients demographic parameters including age, main complaint(s), previous surgery type, time to diagnosis were analyzed. Also operative time, hospitalisation lenght, perioperative and postoperative complication( s) were evaluated. RESULTS: Five patients had undergone tension free vaginal tape procedure and one patient had undergone transobturator tape procedure. Median age was 62 (50-71) years. In one patient bladder stone formed around an intrauterine device. Dysuria (85%), hematuria (57%) and recurrent urinary tract infection (57%) were the main complaints. The median diagnosis time was 44.1 months. Abdominal ultrasonography and non contrast enhanced computer tomography were performed for five and two patients respectively and diagnosis was confirmed cystoscopically. Endoscopic lithotripsy using Holmium laser lithotripter or pneumatic lithotripter was used for all cases. The mean operation time was 41.2 minutes (20-70) and success was 100%. There was no intraoperative complication. Only one patient had fever higher than 38ºC postoperatively and was treated by appropriate antibiotic. The median hospitalisation time was 1.57 day. CONCLUSION: In conclusion endoscopic lithotripsy is a safe and effective approach to manage bladder stone associated with mid-urethral synthetic slings and intrauterine devices.

OBJECTIVES: To evaluate the potential benefits of laparoendoscopic single-site pyeloplasty over conventional laparoscopic pyeloplasty. METHODS: Between October 2009 and January 2012, 39 patients were enrolled in a prospective study and randomized to undergo a laparoendoscopic single-site pyeloplasty (n = 19) or conventional laparoscopic pyeloplasty (n = 20). The outcomes in the two groups were compared by using Mann-Whitney U-test and χ(2) -test, and considering a P-value less than 0.05 as statistically significant. RESULTS: There was no difference in blood loss (55.67 ± 6.71 vs 45.84 ± 5.22 mL, P = 0.60), transfusion rates (0% for both) and hospitalization time (2.12 ± 0.23 vs 2.06 ± 0.34 days, P = 0.72) between the laparoendoscopic single-site pyeloplasty and conventional laparoscopic pyeloplasty groups. The time to return to normal activities was shorter (8.65 ± 1.25 vs 11.53 ± 1.28 days, P = 0.01), and median operative time (195.21 ± 12.15 vs 145.62 ± 15.34 min, P = 0.001) was longer in the laparoendoscopic single-site pyeloplasty group compared with the conventional laparoscopic pyeloplasty group. No significant intraoperative or postoperative complications occurred in either group. Compared with conventional laparoscopic pyeloplasty, laparoendoscopic single-site pyeloplasty yielded better cosmetic results and patient satisfaction. The mean follow-up period was 19.7 months (4-28 months). The success rate was 95% in both the groups. Both the visual analog scale and the postoperative use of analgesics were significantly lower in patients who underwent laparoendoscopic single-site pyeloplasty. CONCLUSIONS: Our findings suggest that laparoendoscopic single-site pyeloplasty can offer faster recovery and higher patient satisfaction than conventional laparoscopic pyeloplasty. Thus, this novel technique promises to become the treatment of choice in minimally-invasive management of ureteropelvic junction obstruction.

BACKGROUND: Robotic-assisted laparoscopic radical prostatectomy (RARP) has increasingly become a preferred treatment of choice. Since it is a device dependant surgery, robotic surgery may be a challenging procedure due to failure. METHODS: We report how we managed to complete successfully a case of RARP with laparoscopic approach in spite of right robotic arm failure during live surgery. RESULTS: A 56-year-old male patient diagnosed with localized prostate cancer (PCa) (Gleason score 3 + 3 = 6) with a serum prostate specific antigen (PSA) level of 7.6 ng/mL was elected for a live RARP case during the 1st Turkish National Robotic Surgery Congress in 2011. Following 120 minutes from starting the RARP procedure, the right robotic arm failed surprisingly with a "recoverable fault" message appeared on the screen. Pressing "recover fault" button did not work and the right arm operated for few seconds more but the fault repeated again. We replaced the robotic instruments, shut down and restarted the system again that were all useless. Finally, all of the arms were out of order and we were not able to use the robot anymore. Therefore, we laparoscopically completed the procedure successfully without converting to open surgery. CONCLUSIONS: Although da Vinci surgical system failure rarely occurs, surgical team should be prepared to convert to open or complete the procedure laparoscopically. Having previous laparoscopic experience seems to be an advantage in order to complete the procedure without converting to open. Patients should be informed about the possibility of robotic failure and about its consequences before the surgery.

OBJECTIVE: We present the transperitoneal and retroperitoneal approaches to laparoscopic partial nephrectomy and compare the outcomes of each technique. METHODS: Between December 2006 and March 2010, retroperitoneal laparoscopic partial nephrectomy (RLPN) was performed in 23 patients and transperitoneal laparoscopic partial nephrectomy (TLPN) in 26 patients. They were compared regarding surgical technique, operative parameters, postoperative recovery and follow-up data. The 2 approaches used similar operative techniques to control parenchymal bleeding. RESULTS: The patient demographics were similar in both groups. The mean tumour size was 3.1 cm in the retroperitoneal group and 3.4 cm in the transperitoneal group. The difference was not statistically significant (p: 0.095). The mean operative time was significantly longer in the transperitoneal group (215 vs 185 minutes, p: 0.031). The mean warm ischemia time difference was not statistically significant (25 vs 28 minutes, p: 0.102). The mean estimated blood loss (EBL) was greater in the transperitoneal group (254 vs 204 cc, p: 0.003). Moreover, the mean hospital stay was 4.1 days in the RLPN and 4.3 days in the TLPN group (p: 0.303) The difference was not statistically significant. The median follow-up was 11 months (range: 2 to 35) in the retroperitoneal group and 13 months (range 1 to 36) in the transperitoneal group. CONCLUSIONS: Our experience has shown that laparoscopic partial nephrectomy is a safe, feasible technique for patients with small exophytic renal tumours. We believe that the decision regarding the approach should be based on the tumor location on the kidney surface.

Extracorporeal shock wave lithotripsy (SWL) is a very commonly used treatment modality for appropriate sized stones. Even though it is a noninvasive treatment technique, major complications may occur following SWL sessions. Herein, we report a 17-year-old male patient, who received 2 sessions of SWL treatment for his left kidney stone, 4 months before his admission. Imaging methods showed an enhanced left renal pelvis mass with contrast-enhanced computerized tomography (CT) and this finding raised a suspicion of pelvis renalis tumor. Diagnostic ureterorenoscopy was planned for the patient and operation revealed a left intrarenal hematoma, which was drained percutaneously during the same operation. Careful history should be taken from patients with renal pelvis masses and intrarenal hematoma formation should be kept in mind, especially if the patient has a previous SWL history.
RESUMO
Pyogenic granulomas are benign vascular disorders of the skin and mucose membranes, generally developed by trauma and irritation. The lesions are generally small. They are most commonly seen in the skin and oral mucosa and rarely seen on penis. We present the case of a huge pyogenic granuloma on the penis.

ABSTRACT Objective We aimed to evaluate the results of laparoscopic pyeloplasty with concomitant pyelolithotomy and compare results with a cohort of patients undergoing laparoscopic pyeloplasty without pyelolithotomy. Materials and Methods We retrospectively reviewed records of 43 patients undergoing transperitoneal laparoscopic Anderson-Hynes dismembered pyeloplasty between December 2012 and July 2018 at our department. Eighteen patients (42%) underwent laparoscopic pyeloplasty with concomitant pyelolithotomy. The results of patients with renal stones were compared with 25 matched patients undergoing laparoscopic pyeloplasty without concomitant renal stones. Demographic data, operative and stone parameters were compared between the groups. Results The groups were similar regarding to demographic characteristics. All operations were completed laparoscopically with no conversions to open surgery. In 3 cases without renal stones and 15 cases with renal stones, transposition of the ureter due to crossing vessels was performed. The mean stone size was 13±5.24 mm, and the median number of stones was 1 (1-18). The success of laparoscopic pyeloplasty with and without pyelolithotomy was 93.3% and 92.9%, respectively, as confirmed by negative diuretic renogram at postoperative 3rd months. Overall stone-free rate after laparoscopic pyelolithotomy was 93.3%. Mean operative time was 222.6765.71 minutes vs. 219.11±75.63 minutes for the pyeloplasty with concomitant pyelolithotomy vs. pyeloplasty, respectively (p=0.88). Conclusions Laparoscopic pyeloplasty with concomitant pyelolithotomy is a safe and effective intervention with associated good cosmetic results and high stone-free rates without significant increase in operative time or complications.

Fournier's gangrene (FG) is a rare and often fulminant necrotizing fasciitis of the perineum and genital region frequently due to polymicrobial infection. This truly emergent condition is typically seen in elderly, diabetic and immune compromised patients. Here, we report an unusual case of FG with isolated glans penis necrosis in a diabetic 77-year-old male patient presented to the emergency department complaining 5 days of pain and darkening of the glans penis. Examination of the patient's glans penis was consistent with FG and included significant erythema and infectious discharge. He was given intravenous antibiotics and emergency debridement was done. On following days, the necrotic area spread to distal parts of both cavernosal areas. Partial penectomy was performed. Isolated penile involvement in FG is very rare. Performing partial penectomy in appropriate cases can save penile length, stop the progression of disease, and increase the quality of life.

OBJECTIVE: To report an international, multi-institutional series of laparoendoscopic single-site pyeloplasty (LESS-P) with analysis of functional outcomes. MATERIALS AND METHODS: LESS-P cases performed between October 2007 and June 2012 at 7 institutions worldwide per individual institutional protocols, entry criteria, and techniques were included. Patient characteristics, operative indications, perioperative outcomes, and postoperative follow-up were retrospectively collected and analyzed. RESULTS: The study included 140 adult patients (age 39.9 ± 15.7 years; body mass index 24.8 ± 4.2 kg/m(2); 15% with previous abdominal surgery) who underwent unilateral LESS-P, most of whom (94.3%) had dismembered reconstructions. Mean operative time was 202.1 ± 47 minutes with an estimated blood loss of 61.2 ± 44.6 mL. Robotic laparoendoscopic single-site surgery was applied in 31 patients (22.1%). A single 2-3 mm accessory port was used in 44 patients (31.4%) and a single 5-12 mm accessory port was added in 9 patients (6.4%), whereas 10 patients (7.1%) were converted to conventional multiport laparoscopy. No patients required conversion to open surgery, nor were any intraoperative complications reported. Length of hospitalization was 2.4 ± 1.6 days. The overall 90-day postoperative complication rate was 18.6%, mostly low-grade complications (Clavien I-II). With a mean follow-up of 14.0 ± 10.8 months, 93.4% had resolution of symptoms and 94.4% had radiographic evidence demonstrating resolution of ureteropelvic junction obstruction. Assessment of drainage with diuretic nuclear renal scan provided evidence of improvement in 86.5% of patients on their first postoperative renal scan. CONCLUSION: This study highlights the most comprehensive experience with LESS-P reported to date. Outcome measures parallel those of large published series of conventional laparoscopic pyeloplasty. Despite these encouraging findings, longer follow-up is needed to determine the efficacy and durability of this approach for the treatment of ureteropelvic junction obstruction.

In this study we report our initial robot-assisted laparoscopic radical prostatectomy (RALRP) experience for organ-confined prostate cancer with the first 112 cases between August 2009 and January 2011. The mean age was 61 (46-76) years. Gleason scores ranged between 4 and 9, and the mean prostate volume was 38.7 (15-115) ml. The mean follow-up time was 8.1 (1-18) months. The mean operative time was 174.7 (75-360) min, and the mean estimated blood loss was 141 (60-800) ml. A nerve-sparing procedure was performed bilaterally in 79 cases and unilaterally in 15 cases. All the complications seen (8 out of 112 patients, 7.1%) were grade 1 and 2 according to the Clavien classsification system. Postoperatively, five (4.4%) patients needed transfusion. Mean drain extraction time was 3.2 (2-15) days and mean hospital stay was 4 (2-18) days. The catheter was removed on postoperative day 8.5 (6-20). Surgical margin was positive in 13 (11.6%) patients. Forty-nine patients have 6 months and 30 patients have 12 months follow-up. The continence rate were 29.4, 64.2, 84.2, 91.1 and 96.6% immediately after catheter removal and at 1, 3, 6 and 12 months, respectively. No anastomotic stricture or urinary retention was seen in the follow-up period. RALRP is a safe and feasible technique in the treatment of localized prostate cancer. Our initial experience with this procedure shows promising short-term outcomes.
RESUMO
PURPOSE: The purpose of this study was to present our initial clinical experience with laparoendoscopic single-site surgery (LESS) for ureteropelvic junction (UPJ) obstruction. PATIENTS AND METHODS: Between May and October 2009, 14 consecutive patients underwent LESS-pyeloplasty (LESS-P) by the same surgeon at our institution. All patients underwent single port transperitoneal Anderson-Hynes laparoscopic dismembered pyeloplasty using the single incision laparoendoscopic surgery port, inserted through a transumbilical incision. Ultrasonography, intravenous urography (IVU) or diuretic renal scan was performed at the third month and semiannually thereafter. Patients were examined clinically every 3 to 6 months, depending on the symptoms. Radiographic success was defined as improvement of hydronephrosis with a patent UPJ on IVU, or improved drainage on diuretic renal scan. RESULTS: Anterior crossing vessels, high insertion, and severe adhesion were found in seven (50%), five (35.7%), and two (14.3%) cases, respectively. The mean operating-room time, which includes cystoscopy with retrograde ureteral catheterization and open-end stent placement, was 204.5 minutes (range 160-300 min), and the mean estimated blood loss, including urine, was 102 mL (range 80-170 mL). Mean hospital stay was 2 days (range 1-3 d). Wound infection occurred in one patient. The mean follow-up period was 6.2 months (range, 3-8 mos). The success rate was 100%. CONCLUSION: With the advent of the single port and laparoscopic instrument technology, the LESS-P, as minimally invasive surgery, would take the place of the standard laparoscopic pyeloplasty, and it may be a new choice for the management of UPJ obstruction.
