RESUMO
OBJECTIVE: To compare the outcomes of the first 40 patients to undergo robot-assisted kidney transplantation (RAKT) with those of the first 40 patients who underwent open KT (OKT) by a single surgeon at the Dr Sadi Konuk Training Hospital. PATIENTS AND METHODS: We prospectively collected the data of the first 40 patients to undergo RAKT between January 2016 and February 2017 (RAKT group), and compared them with the first 40 patients to undergo OKT between November 2010 and April 2015 (OKT group). Comparisons were made using one-way analysis of variance or the Kruskal-Wallis test for continuous variables, and the chi-squared or Fisher's exact test for categorical variables. RESULTS: There were 40 patients in both the RAKT and OKT groups. In the RAKT group, the mean (SD) operative time was 265.375 (46.63) min, total ischaemia time was 96.7 (30.02) min, re-warming time was 54.70 (17.80) min, and estimated blood loss (EBL) was 182.25 (55.26) mL. Whilst in the OKT group the mean (SD) operative time was 250.25 (41) min (P = 0.129), total ischaemia time was 71.79 (8.55) min (P < 0.01), re-warming time was 37.30 (4.07) min (P < 0.001), and EBL was 210.75 (28.96) mL (P = 0.005). At 12-24 h postoperatively, linear visual analogue scale pain scores were significantly lower in the RAKT group (P < 0.001), and the RAKT group had a significantly shorter drain withdrawal time, at a mean (SD) of 3.45 (0.93) vs 7.67 (2.11) days in the OKT group (P < 0.001). CONCLUSION: Satisfactory functional outcomes can be achieved by either OKT or RAKT. However, the latter technique seems to have some advantages over the former in that it is less invasive, results in less pain postoperatively, has a shorter drain withdrawal time, and has the potential for fewer complications.

OBJECTIVE: To compare standard urotherapy with a combination of urotherapy and biofeedback sessions and to determine the changes that these therapies promote in children with dysfunctional voiding. PATIENTS AND METHODS: The data of 45 patients who participated in the study from January 2010 to March 2013 were evaluated. All patients underwent urinary system ultrasonography to determine post-void residual urine volumes and urinary system anomalies. All patients were diagnosed using uroflowmetry - electromyography (EMG). The flow pattern, maximum flow rate, and urethral sphincter activity were evaluated in all patients using uroflowmetry - EMG. Each patient underwent standard urotherapy, and the results were recorded. Subsequently, biofeedback sessions were added for all patients, and the changes in the results were recorded and statistically compared. RESULTS: A total of forty - five patients were included, of which 34 were female and 11 were male and the average age of the patients was 8.4 ± 2.44 years (range: 5 - 15 years). After the standard urotherapy plus biofeedback sessions, the post-void residual urine volumes, incontinence rates and infection rates of patients were significantly lower than those with the standard urotherapy (p < 0.05). A statistically significant improvement in voiding symptoms was observed after the addition of biofeedback sessions to the standard urotherapy compared with the standard urotherapy alone (p < 0.05). CONCLUSIONS: Our study showed that a combination of urotherapy and biofeedback was more effective in decreasing urinary incontinence rates, infection rates and post - void residual urine volumes in children with dysfunctional voiding than standard urotherapy alone, and it also showed that this combination therapy corrected voiding patterns significantly and objectively.

PURPOSE: We aimed to compare the outcomes of pneumatic (PL), ultrasonic (UL) and combined (PL/UL) lithotripsy performed in percutaneous lithotripsy (PNL) according to success rates and stone clearence. MATERIALS AND METHODS: The medical records of 512 patients treated with PNL between April 2010 and April 2013 were evaluated. Postoperative stone analysis revealed as calcium oxalate in 408 of these patients. The operation notes of 355 patients recorded in detail with complete parameters were reviewed. According to stone disintegration method, patients were divided into three groups: PL only in Group I, UL only in Group II, and UL/PL combination in Group III. Number of patients was 155, 110 and 90, respectively. RESULTS: Fluoroscopy screening time was significantly shorter in group II, and III compared to group I (p<0.001). The failure rates were 13.5% (21 patients) for group I, 3.6% (4 patients) for group II, and 3.3% (3 patients) for group III. There was a significant statistical difference in favor of group II and III by means of success (p=0.023). Group II and III had larger FSA, and this was statistically significant (p=0.032). Stone disintegration time (SDT) was 64.0 ± 41.92 minutes for group I, 49.5 ± 34.63 for group II, and 37.7 ± 16.89 for group III. Group III has a statistically significant shorter SDT (p=0.011). CONCLUSIONS: We concluded that, in cases with high stone burden, where faster and efficient lithotripsy is needed, combined ultrasonic / pneumatic lithotripter may be the ideal choice and in suitable cases ultrasonic lithotripter usage provides important advantages to the surgeon.

We aimed, in this study, to determine the distribution of α-1 AR subtypes in rat and human pelvis and calyces, and to evaluate, by comparing these two species, the possibility of rats to be used as models for humans. Twenty patients with renal carcinoma were included into the study. The patients underwent radical nephrectomy for renal cell carcinoma (RCC). After nephrectomy, specimens were evaluated and excisional biopsies from healthy pelvis and calyces tissues were performed. When pathology confirmed the non-invasion of RCC, specimen was included into the study. A total of 7 adult Wistar Albino (250-300 g) female rats were used in this study. Specimens included renal pelvis and calyces. All specimens were evaluated under light microscope histopathologically. The concentrations of the receptor densities did not differ between the two groups. With the demonstration of the α receptors in rat kidneys and calyces, many receptor-based studies concerning both humans and rats can take place. Novel medication targeting these subtypes -in this matter α1A and α1D for renal pelvis and calyces- may be helpful for expulsive therapy and/or pain relief. With the demonstration of similar receptor densities between human and rat tissues, rat model may be useful for α-receptor trials for renal pelvis and calyces.

OBJECTIVE: To compare the results of percutaneous nephrolithotomy (PCNL), shock wave lithotripsy (SWL), and retrograde intrarenal surgery (RIRS) for 1- to 2-cm lower pole kidney stones. PATIENTS AND METHODS: This retrospective study was based on data collected from the files of patients between January 2007 and May 2012. The files of 383 patients (221 SWL, 144 PCNL, 38 RIRS) were evaluated. The groups were compared for stone size, success rate, and complication rate using the modified Clavien grading system. RESULTS: The stone burdens of the groups were similar (p = 0.36). The success rates were 76, 94, and 73%, respectively, in SWL, PCNL, and RIRS. The highest stone-free rate was in the PNL group (p < 0.05). When the complication rates were evaluated using the Clavien grading system, they were determined to be 13% in PCNL, 3% in SWL, and 5% in RIRS. Especially GII and GIII complications were more common in the PCNL group (p < 0.05). CONCLUSION: PCNL seems to be the most successful but most invasive method. However, with relatively low complication rates, SWL and RIRS are other techniques to keep in mind. To determine the first-line treatment, prospective randomized studies with larger series are needed.

PURPOSE: To evaluate the long term efficacy and safety of the use of propiverine and terazosine combination in patients with LUTS and DO by a placebo controlled study. MATERIALS AND METHODS: One hundred patients were enrolled in the study. They were randomized into two groups (each group consisted of 50 patients). Terazosine and placebo were administered to the patients in Group 1 and terazosine plus propiverine HCL was administered to Group 2. The patients were evaluated by international prostate symptom score (IPSS), the first four questions of IPSS (IPSS4), the 8th question of IPSS (quality of life-QoL), overactive bladder symptom score questionnaire (OAB-q V8), PSA test, urodynamic studies, post voiding residue (PVR). All patients were followed for one year and were reassessed for comparison. RESULTS: IPSS, IPSS4, OAB symptoms, QoL score, PVR, and Qmax scores of the groups did not differ. After one year treatment, there was significant improvement in IPSS, IPSS4, OAB symptoms, QoL and Qmax values in Group 2. No significant improvement was noted for the same parameters in Group 1. CONCLUSION: This is the first study to show long term safety and efficacy of anticholinergic therapy for patients with LUTS. In patients with OAB or DO, long term anticholinergic treatment may be regarded as a treatment option.

We aimed to investigate the impact of metabolic syndrome (MetS) on the varicocele treatment. 101 patients underwent spermatic vein ligation between 2007 and 2010 were retrospectively analyzed. Those patients were divided into two groups as without (n: 56, Group 1) or with MetS (n: 48, Group 2). All the patients underwent left microsurgical subinguinal spermatic vein ligation. Groups were compared by the improvement on sperm parameters and spontaneous pregnancy rates at a mean of 19 (±4) months followup. When sperm parameters were compared postoperatively, the significant improvement in total sperm count, motile sperm count percentage, and normal sperm percentage was reported. The groups were compared to each other and the improvement seemed significantly better in Group 1. There was no statistically significant improvement difference in the normal sperm percentage between groups. Spontaneous pregnancy rate after two years was 45% in Group 1 and 34% in Group 2 (P < 0.05). Patients with MetS and varicocele improved after surgery, but not as well as the similar group without MetS. This may help to show that MetS can be a factor for male infertility.

PURPOSE: To compare totally tubeless and standard percutaneous nephrolitotomy procedures on many parameters. MATERIALS AND METHODS: Percutaneous nephrolitotomy was performed on 195 patients between June 2009 and May 2012. The data of those patients were evaluated retrospectively. Totally tubeless cases were enrolled to Group 1, and Group 2 consisted of non-tubeless cases (re-entry or Foley catheter). RESULTS: Group 1 included 85 cases and group 2 a total of 110 patients. Paper tracing values for the kidney stones were 321.25 ± 102.4 mm(2) and 324.10 ± 169.5 mm(2) respectively. Mean fluoroscopy time was 4.9 ± 1.9 min and 5.08 ± 2.7 min, mean operation time was 78.8 ± 27.9 min and 81.9 ± 28.77 min and mean decrease in hematocrit was 2.6 ± 1.6 and 3.74 ± 1.9 respectively. All these comparisons were statistically significant. Length of hospitalization was 1.6 ± 1.1 and 3.5 ± 1.5 days for Groups 1 and 2 respectively. Mean superficial pain score was 5.8 ± 1.6 and 6.7 ± 1.2 respectively for both groups after 1 hour. At 6 hours, the scores changed to 3.87 ± 1.22 and 4.84 ± 1.3 respectively. The analgesic dose was 1.00 ± 0.7 and 1.53 ± 0.6 for the groups respectively at 6 hours. All the statistical differences were significant for these three parameters. CONCLUSIONS: We believe that, because of their post operative patient comfort and decreased length of hospital stay, totally tubeless procedures should be considered as an alternative to standard percutaneous nephrolitotomy.

Aim of this study is to categorize stones between 10 and 20 mm according to stone diameter or volume and compare mini percutaneous nephrolithotomy (mPNL) and retrograde intrarenal surgery (RIRS) outcomes. Files of 515 patients who underwent surgery for kidney stones with sizes 10-20 mm were reviewed. Patients were divided into RIRS or mPNL groups. An attempt was made to find the diameter and volume threshold values above which the success of the operation, complication rates and the number of auxiliary treatments deteriorated. Subgroup analysis was performed below and above the threshold value to reveal the optimal treatment methods. RIRS complications increased with volumes above 1064 mm3, number of auxiliary interventions increased with volumes above 1256 mm3, and success of the operation decreased with volumes above 1416 mm3. A subgroup analysis under and over 1064 mm3 was performed in RIRS group. Complication and auxiliary treatment rates were higher, operative success was lower in patients with a stone volume greater than 1064 mm3. In patients who underwent RIRS, for every 1000 mm3 increase in stone volume success of the operation decreased by 2.1 times, while the probability of auxiliary treatment increased by 2.8 times. In patients with kidney stones between 10 and 20 mm, it is more meaningful to use volume instead of diameter to determine the success rate. When mPNL is used instead of RIRS for volumes greater than 1064 mm3, the success rate will be higher, complication rate will be similar, and the need for auxiliary treatment will be lower.

PURPOSE: Comparing the two different drainage methods of percutaneous nephrostomy (PCN) versus retrograde ureteral double - J (DJ) stent insertion in patients with obstructive pyelonephritis cases. MATERIAL AND METHODS: In this retrospective study, patients with obstructive pyelonephritis secondary to urolithiasis who underwent PCN or DJ insertion were included in the study. Patients were divided into two groups according to drainage method. After exclusion criteria, the study included 105 patients. The groups were compared for intraoperative outcomes, duration of fluoroscopy usage, the time needed for normalization of infection parameters (white blood cells (WBC), C - reactive protein (CRP), procalcitonin), and complications were observed. RESULTS: From 105 patients, 56 patients were in DJ stent group and 49 patients were in PCN group. According to intraoperative data, operative time and fluoroscopy duration were significantly shorter in the DJ ureteral stent group (P < .001). WBC returned to normal range in mean 3.5 ± 1.3 days in the DJ stent group and 3.2 ± 1.1 days in the PCN group (95% CI: -0.76-0.21, P = .268). There were no statistically significant differences identified for the duration for CRP, PCT and fever to return to normal range between the drainage methods. The complication rates was 51.8% for DJ stent group and, 30.6% in PCN group (P = .028). CONCLUSION: Both methods are effective and safe in obstructive pyelonephritis. Despite the higher complication rate in DJ stent group, these complications were minor.

OBJECTIVE: Kidney stones in renal pelvis may be treated using various methods. For larger stones, percutaneous nephrolitotomy (PNL) is the first choice of option; where for smaller stones, shock wave lithotripsy (SWL) or flexible ureteroscopy (F-URS) could be more suitable options. In this article we aimed to compare the outcomes of F-URS and SWL on the treatment of renal pelvis stones <10 mm. MATERIAL AND METHODS: Files of patients treated with SWL and F-URS for renal pelvis stones <10 mm between March 2013 and May 2016 in our clinic were analyzed. For comparison, a match-pair analysis was designed. Complete stone removal was considered success. RESULTS: Forty patients were treated using F-URS (Group 1) and 40 patients underwent SWL (Group 2). Patients were assessed the day after the last session of the procedure. The early stone-free rates were 70% (28/40) in Group 1, and 15% in Group 2 (p<0.05). The same analysis was performed after three months. Stone-free rates were 100% and 92.5% in Groups 1 and 2, respectively (p=0.079). Three patients in Group 2 were not stone free after 3 sessions of SWL and considered unsuccessful. They were all successfully treated by F-URS. CONCLUSION: Even though there is no statistical difference among groups, our data may be interpreted as having better outcomes and tolerability with F-URS than SWL. We believe F-URS may have a great treatment prospect in this particular patient group.
RESUMO
PURPOSE: The ischemia and subsequent reperfusion (IR) which occurs in partial nephrectomy used in the treatment of renal tumors causes loss of parenchyma in the damaged kidney. The aim of this study is to evaluate, both biochemically and histologically, the efficacy of esomeprazole in an ischemia-reperfusion model in rat kidneys. METHODS: The rats were randomized into three groups of seven animals each, referred to as the sham, control, and PPI groups. In the sham group, only a laparotomy was performed. In the control group, following laparotomy the left renal artery was dissected and tied for 30-min ischemia. In the PPI group, a vascular route to the tail vein was opened, and 10 mg/kg esomeprazole was administered. After 1 h, the same procedures described for the control group were performed. All the animals were killed 24 h after the procedure. Biochemical analyses were applied for evaluation of oxidant and antioxidant agents in the blood and left kidney of each subject (oxidative markers: malondialdehyde, myeloperoxidase; antioxidant marker: superoxide dismutase). In the histological examination of the kidney tissues stained with hematoxylin-eosin, the TUNEL method was applied in the evaluation of apoptosis. RESULTS: No statistically significant biochemical difference was determined in the blood and tissue samples. In the histological and apoptosis evaluations, a statistically significant difference was determined between the sham, control, and PPI groups. The median (IQR) values of the TUNEL-positive cells were counted as 1.50 (4) in the sham group, 11.50 (12) in the control group, and 6.00 (9) in the PPI group (p < 0.001). CONCLUSIONS: A protective effect of esomeprazole was confirmed in renal ischemia-reperfusion damage created in an experimental rat model.

OBJECTIVE: To present our experience with laparoscopic donor nephrectomy (LDN), our complications and management modalities. Material and methods: Fifty-one transperitoneal LDNs performed in our clinic between the years 2011, and 2015, were evaluated retrospectively. Demographic characteristics of the patients, operative and postoperative data and complications were evaluated. RESULTS: Nineteen female and 32 male patients with ages ranging from 24 to 65 years underwent left- (n=44), and right-sided (n=7) LDNs. Six patients had two, and one patient three renal arteries. Mean operation time was 115±11 (min-max: 90-150) minutes, and mean warm ischemia time 111±9 (min-max: 90-140 sec) seconds. Mean hospital stay was found to be 2.5±0.5 days. No patient needed to switch to open surgery. In one patient, lumbar vein was ruptured, and hemostatic control was achieved laparoscopically. Postoperative paralytic ileus developed in two patients. Three patients had postoperative atelectasis, and a febrile (38.1°C) episode. CONCLUSION: LDN is a minimally invasive method with advantages of short hospital stay, less analgesic requirement, and better cosmetic results. However it should be performed by surgeons with advanced laparoscopic experience.
RESUMO
BACKGROUND AND OBJECTIVE: The present study retrospectively analyzed the data of 213 patients who underwent laparoscopic ureterolithotomy. METHODS: We retrospectively analyzed the data of 213 patients, in whom we performed conventional laparoscopic ureterolithotomy from April 2006 and January 2015 based on the diagnosis of an upper or middle ureteral stone. Patients with large ureteral stones (>15 mm) or a history of failed shock-wave lithotripsy or ureteroscopy were included in the study. Although the retroperitoneal approach was preferred for 170 patients, the transperitoneal approach was used in the remaining 43 patients. RESULTS: The mean patient age was 39.3 ± 12.0 years (range, 18-73). The study population was composed of 78 (26.7%) female and 135 (63.3%) male patients. The mean stone size was 19.7 ± 2.5 mm. The mean operative time was 80.9 ± 10.9 minutes, and the mean blood loss was 63.3 ± 12.7 mL. Intraoperative insertion of a double-J catheter was performed in 76 patients. The overall stone-free rate was 99%. No major complication was observed in any patient. However, conversion to open surgery was necessary in 1 patient. CONCLUSION: With high success and low complication rates, laparoscopic ureterolithotomy is an effective and reliable method that ensures quick recovery and may be the first treatment option for patients with large, impacted ureteral stones, as well as for those with a history of failed primary treatment.

OBJECTIVE: Robotic kidney transplantation, first described by Hoznek and colleagues, and has been improved by investigators like Oberholzer and Menon. We realized the first robotic kidney transplant (RKT) in our clinic in December 2015. In this study, we aimed to present the first 15 cases we performed within 3 months. MATERIAL AND METHODS: Starting from January 2016, we performed 15 RKTs in our hospital. Before surgery, the whole robotic procedure was thoroughly explained to the patients and their informed consents were taken. RESULTS: We performed RKT in 7 male and 8 female patients. Mean patient age was 37.4±10.8 years. Mean body mass index of the patients was 22.6±3.35 kg/m2. Mean preoperative creatinine and hemoglobin levels were 6.14±2.12 mg/dL and 10.04±1.64 g/dL, respectively. Mean operative time was 300.3±104.2 minutes. Mean warm ischemia and re-warming times were 1.9±0.54 minutes and 73.3±30.7 minutes, respectively. We did not need any necessity to switch to open surgery, and any intraoperative complication did not develop in any patient. Lymphocele which is one of the most frequently encountered complications was not observed in our series. CONCLUSION: We think that using a minimally invasive approach greater number of patients will be able to benefit from this treatment modality, and this important health issue may decrease significantly.
RESUMO
PURPOSE: To report and discuss the treatment of ipsilateral upper ureteral and renal stones by laparoscopic ureterolithotomy with concomitant pyelolithotomy using flexible cystoscope. MATERIALS AND METHODS: A total of 19 patients (14 men and 5 women) underwent laparoscopic retroperitoneal ureterolithotomy with concomitant pyelolithotomy using flexible cystoscope through the ureterotomy site. The mean age of the patients was 37.9 (22-61) years. Stones were on the right side in 12, on the left side in 7, and multiple in 6 patients. All ureteral stones were located in the upper ureter. Most renal stones were in the pelvis or in the calices. RESULTS: All procedures were completed laparoscopically without conversion to open surgery. Mean operation duration was 86.5 (range: 80-93) minutes, thus operation duration was prolonged by a mean of 24.4 minutes in patients with concomitant stone extraction. Fifteen cases were treated using flexible cystoscope and a nitinol basket; in the remaining four cases holmium laser lithotripsy was performed. Complete stone clearance was confirmed by postoperative imaging in all patients. CONCLUSIONS: Laparoscopic ureterolithotomy with concomitant pyelolithotomy is a feasible and effective technique for patients with large ureteral stone and low renal stone burden. .

BACKGROUND AND OBJECTIVES: Robot-assisted laparoscopic radical prostatectomy (RALRP) is said to provide excellent long-term continence. In this study, we compared the early incontinence outcomes of our patients, who had undergone no reconstruction, posterior reconstruction only, or total anatomic restoration and posterior reconstruction. METHODS: We retrospectively analyzed the patients who underwent RALRP for localized prostate cancer by a single surgeon in our clinic from January 1, 2009-February 1, 2016. Continence was defined as no leakage or use of a safety pad for minimal leakage. The main outcome measure was continence at postoperative week 1 and months 1, 6, and 12. RESULTS: Between 2009 and 2016, 239 patients underwent RALRP for localized prostate disease. Seventy-four patients underwent a standard approach (group 1), 88 had posterior reconstruction (group 2), and 77 had posterior reconstruction with total anatomic restoration (group 3). After 1 week, 24.3% of the patients in group 1 (18/74), 31.8% in group 2 (28/88), and 45.8% in group 3 (33/72) were continent (P = .02). One month after the surgery, continence rates for groups 1, 2, and 3 were 56.7, 67, and 75%, respectively (0.065). After 6 and 12 months, continence rates for groups 1, 2, and 3 were 72.9 and 87.8%, 81.8 and 89.7%, and 84.7 and 91.6%, respectively (P = .178 and .7484). CONCLUSION: Anatomic restoration improves continence rates in the early period after RALRP. Even though other parameters were higher in the total restoration group, immediate continence (at 1 week) was significantly better.

BACKGROUND: Different energy sources can be used for ureteroscopic stone fragmentation, such as pneumatic, ultrasonic, laser or electrohydraulic. The aim of this study was to compare the efficacy and safety of pneumatic lithotripters versus Ho: YAG laser in the treatment of multiple stones in the distal ureter. METHODS: A retrospective evaluation was done using the data of patients to whom ureteroscopic lithotripsy (URL) was applied for ureter stones in our clinic. From these patients, those with multiple unilateral distal ureter stones were identified, then these patients were separated into 2 groups according to the type of lithotriptor used in stone fragmentation as laser lithotripsy (Group 1) and pneumatic lithotripsy (Group 2). RESULTS: Statistically, the two groups were similar in respect of the number of stones, stone burden and the number of double J stents applied intra-operatively. The mean operating time was similar in the 2 groups as 53.47 (±17.3) minutes in Group 1 and 50.59 (±15.3) minutes in Group 2. On postoperative day 1 after the URL, the stone free rate (SFR) of Group 1 (78.7%) was found to be significantly high compared to the SFR of Group 2 (63.6%), while at postoperative month 1, the SFR of both groups was found to be similar. Binary logistic regression was applied to determine the effect of related independent variables on the 1st month SFR. In this model, age and stone burden were affecting variables. CONCLUSION: Compared to the pneumatic lithotripter, the Ho: YAG laser seems to have advantages of a higher SFR in the early postoperative period, eventhough there are statistically similar success rates and complication rates.
