RESUMO
OBJECTIVE: To externally validate Yonsei nomogram. METHODS: From 2000 through 2018, 3526 consecutive patients underwent on-clamp PN for cT1 renal masses at 23 centers were included. All patients had two kidneys, preoperative eGFR ≥60 ml/min/1.73 m2, and a minimum follow-up of 12 months. New-onset CKD was defined as upgrading from CKD stage I or II into CKD stage ≥III. We obtained the CKD-free progression probabilities at 1, 3, 5, and 10 years for all patients by applying the nomogram found at https://eservices.ksmc.med.sa/ckd/. Thereafter, external validation of Yonsei nomogram for estimating new-onset CKD stage ≥III was assessed by calibration and discrimination analysis. RESULTS AND LIMITATION: Median values of patients' age, tumor size, eGFR and follow-up period were 47 years (IQR: 47-62), 3.3 cm (IQR: 2.5-4.2), 90.5 ml/min/1.73 m2 (IQR: 82.8-98), and 47 months (IQR: 27-65), respectively. A total of 683 patients (19.4%) developed new-onset CKD. The 5-year CKD-free progression rate was 77.9%. Yonsei nomogram demonstrated an AUC of 0.69, 0.72, 0.77, and 0.78 for the prediction of CKD stage ≥III at 1, 3, 5, and 10 years, respectively. The calibration plots at 1, 3, 5, and 10 years showed that the model was well calibrated with calibration slope values of 0.77, 0.83, 0.76, and 0.75, respectively. Retrospective database collection is a limitation of our study. CONCLUSIONS: The largest external validation of Yonsei nomogram showed good calibration properties. The nomogram can provide an accurate estimate of the individual risk of CKD-free progression on long-term follow-up.

OBJECTIVES: To evaluate the impact of the prostatic-urethral angulation (PUA) on the treatment efficacy of selective alpha-1A receptor blocker in male patients with lower urinary tract symptoms secondary to benign prostatic hyperplasia (LUTS/BPH). MATERIALS AND METHODS: A total of 80 patients with LUTS/BPH and with mean age 53.3 ± 6.3 (range 47-70) were included in our prospective comparative study. The patients were classified into 2 groups as a consecutive cases 40 in each one depending on the PUA either ≤ 35° (group A) or > 35° (group B). PUA and different prostatic parameters were measured using transrectal ultrasound. Prostate-specific antigen (PSA), the International Prostate Symptom Score and quality of life score (IPSS/QoL score), maximum flow rate (Qmax), and postvoid residual (PVR) volume were compared between the groups. The clinical significance of PUA was evaluated after 8 weeks of medical treatment with tamsulosin hydrochloride 0.4 mg daily. RESULTS: Baseline evaluation (pre-treatment) for both groups were comparable to each other with no clinically significant difference regarding age, PSA, IPSS/QoL score, Q(max) and PVR volume (P-value > 0.05). Comparison of parameters after 8 weeks showed that tamsulosin hydrochloride improved the total IPSS and all subscores (P < 0.001), QoL (P = 0.001), Q(max) (P = 0.002), and PVR (P = 0.04) in group A (Table 1). CONCLUSION: Tamsulosin hydrochloride appears to be less effective in improving IPSS/Qol score, Qmax and PVR in patients with lager PUA. The PUA might be a predictor for the treatment efficacy of α-blockers and more studies are warranted in the future before the final conclusion.

Context: Dutasteride is used in the treatment of benign prostate enlargement with reported many side effects. Aims: The purpose of this study is to examine how different doses of dutasteride (0.5 mg) in combination with tamsulosin affect the outcome of treatment of benign prostatic enlargement (BPE). Settings and Design: Prospective study (phase III trial). Subjects and Methods: Between April 2017 and March 2020, this randomized study was conducted on 300 patients with moderate-to-severe lower urinary tract symptoms attributable to BPE and a prostate volume of more than 40 cc. The patients were divided into three therapy groups at random (one-to-one randomization), each with 100 patients: (Group I) daily tamsulosin 0.4 mg plus dutasteride (0.5 mg). (Group II) every other day tamsulosin 0.4 mg plus dutasteride 0.5 mg. (Group III) once a week tamsulosin 0.4 mg plus dutasteride 0.5 mg. Statistical Analysis: Statistical analysis was carried out with the help of the SPSS program 22. (IBM, Armonk, NY, USA). The mean and standard deviation (SD) are used to express quantitative data (SD). When comparing two means, an independent-samples t-test of significance was used. To compare more than two means, a one-way analysis of variance was utilized. For multiple comparisons between distinct variables, a post hoc test was performed. Results: Patients were followed up every 3 months, with a 1-year follow-up to examine the medications' efficacy, prostate size reduction, and erectile function. After 1 year of treatment, all groups showed significant improvement in their symptom scores. However, Groups I and II experienced a considerable reduction in prostate size after therapy, but Group III experienced no meaningful reduction. In terms of sexual dysfunction, there was a considerable shift in Group I after 12 months. Conclusions: Dutasteride treatment on the other day schedule has the same efficacy as the daily dose on prostate size at the same time; the other day scheduled dose has better preservation of sexual function.
RESUMO
This study aimed at assessing a new line of treatment for lifelong premature ejaculation which is botulinum-A toxin injection into the bulbospongiosus muscle. Sixty patients with lifelong premature ejaculation were independently randomized into 2 groups; group I, 100 U botulinum-A toxin at 10 U/ml saline was injected with ultrasound guidance into the bulbospongiosus muscle and group II which was injected with similar volume of saline. The primary outcome was to compare both groups for changes in the Premature Ejaculation Profile (PEP), Intravaginal Ejaculatory Latency Time (IELT) and partner's satisfaction at 1, 3 and 6 months after intervention. The second outcome was to compare the adverse events in both groups. Fifty-seven patients completed the study. In group I, the mean PEP increased significantly at 1- (P = 0.02) and 3- months (P = 0.04) with insignificant increase at 6-month (P = 0.6) of follow-up. Also, no significant changes had been noted in IELT or partner's satisfaction scores throughout the study duration (P > 0.05). In group II, no significant changes had been noted in the PEP, IELT and partner's satisfaction scores throughout the study duration (P > 0.05). There were insignificant differences in the changes in the mean PEP (P = 0.7, 0.6 and 0.4), IELT (P = 0.6,0.6 and 0.5) and partner's satisfaction scores (P = 0.5,0.7 and 0.3) in comparison to the baseline values at 1-, 3- and 6- months, respectively between both groups. Adverse events were observed in only 3 patients (5.3%). In group I, mild erectile dysfunction and post micturition dribbling were reported in one patient each. Where in group II, one patient reported bleeding per urethra (P = 0.5). To conclude, injection of botulinum-A toxin into bulbospongiosus seems to be safe but failed to prove clinical efficacy for treatment of lifelong premature ejaculation when compared to placebo.
RESUMO
INTRODUCTION: Donor nephrectomy (DN) is a unique surgical procedure in urological practice, as it involves exposing a healthy individual to the potential risks of surgery. This type of surgery exhibits heterogeneity in terms of approach (open, laparoscopic, or robotic), each with its unique set of advantages and disadvantages. Consequently, there is currently a lack of universally agreed upon clear guidelines. In these settings, this study aims to evaluate transplantation surgeons' knowledge through a real-life survey and compare it with data from published randomized controlled trials (RCTs). EVIDENCE ACQUISITION: The study is divided into two parts, with the first part focusing on the outcomes of the real-life survey designed to assess surgeons' knowledge about different DN approaches and their real-world practices during the surgery. The second part involves a systematic review and meta-analysis of RCTs, specifically examining the outcomes of different surgical approaches to DN. The systematic review followed the PRISMA Guidelines and involved a search of PubMed and Web of Science for RCTs comparing the outcomes of different DN approaches. The risk of bias was assessed using the RoB-2 tool. The random effect model was mainly used to assess the mean difference of the included studies. EVIDENCE SYNTHESIS: The study was conducted between July 2021 and January 2022 and surveyed 50 surgeons, of which 35 participants (70%) completed the survey. Regarding various approaches to DN, 97.14% of surgeons reported having experience with live DN, and 45.72% performed over 15 cases per year. The most performed approach was pure laparoscopic DN (68.57%). Pure laparoscopic DN was the preferred approach for 77.42% of respondents. The review process resulted in 335 articles, of which 35 were eligible for inclusion in the systematic review. In summary, most studies found that laparoscopic approaches, including standard, hand-assisted, LESS-DN, and mini-LDN, resulted in less postoperative pain, better cosmetic, and quicker recovery times compared to open approaches. The main limitation of the current study is the heterogeneity of the included studies. CONCLUSIONS: The study provides valuable insights into the practices of renal transplantation surgeons, offering a comprehensive comparison to level 1 studies (RCTs) in the field. It underscores the continued significance of ODN in contemporary practice, particularly in light of recommendations from the EAU guidelines on renal transplantation. This reaffirms the need to consider the advantages and disadvantages of various approaches, including factors such as cost, postoperative pain, and cosmetic outcomes. While robotic-assisted DN holds promise, their adoption remains variable, potentially due to limited robust evidence.

OBJECTIVES: We evaluated the baseline characteristics, and risk factors of renal stone recurrence among Saudi Arabian patients after successful primary stone treatment. MATERIALS AND METHODS: In this cross-sectional comparative study, we reviewed the medical records of patients who presented consecutively with a first renal stone episode from 2015 to 2021 and were followed-up by mail questionnaire, telephone interviews, and/or outpatient clinic visit. We included patients who achieved stone-free status after primary treatment. Patients were divided into two groups: group I (patients with first episode renal stone) and group â ¡ (patients who developed renal stone recurrence). The study outcomes were to compare the demographics of both groups and to evaluate the risk factors of renal stone recurrence after successful primary treatment. We used Student's t-test, Mann Whitney test or chi-square (x2) to compare variables between groups. Cox regression analyses were used to examine the predictors. RESULTS: We investigated 1260 participants (820 males and 440 females). Of this number, 877 (69.6%) didn't develop renal stone recurrence and 383 (30.4%) had recurrence. Primary treatments were percutaneous nephrolithotomy (PCNL), retrograde intrarenal surgery (RIRS), extracorporeal shock wave lithotripsy (ESWL), surgery and medical treatment in 22.5%, 34.7%, 26.5%, 10.3%, and 6%, respectively. After primary treatment, 970 (77%) and 1011 (80.2%) of patients didn't have either stone chemical analysis or metabolic work-up, respectively. Multivariate logistic regression analysis revealed that male gender (OR: 1.686; 95% CI, 1.216-2.337), hypertension (OR: 2.342; 95% CI, 1.439-3.812), primary hyperparathyroidism (OR: 2.806; 95% CI, 1.510-5.215), low fluid intake (OR: 28.398; 95% CI, 18.158-44.403) and high daily protein intake (OR: 10.058; 95% CI, 6.400-15.807) were predictors of renal stone recurrence. CONCLUSIONS: Male gender, hypertension, primary hyperparathyroidism, low fluid intake and high daily protein intake increase the risk of renal stone recurrence among Saudi Arabian patients.

INTRODUCTION: Dysfunctional voiding is a multifactorial condition that encompasses a wide variety of symptoms rendering its diagnosis a challenging process. In this setting, several tools have been proposed to aid the diagnosis of this disease among which is the Dysfunctional Voiding Symptom Score (DVSS). The DVSS has been translated and validated to different languages including Japanese, Thai, Chinese, Serbian, and Portuguese. The aim of the current study is to translate and cross-culturally validate the DVSS into the Arabic language. MATERIAL AND METHODS: The DVSS was translated and culturally adapted to the Arabic language following the standards of the ISPOR for the translation and cultural adaptation process for patient-reported outcomes measures. Subsequently, the translated version underwent a pre-test on 15 patients with dysfunctional voiding. Afterwards, the translated version was filled by 82 pediatric patients and/or their parents with dysfunctional voiding and then the same questionnaire was refilled by the patients and their families one week later at home. Finally, a group of healthy children and/or their parents were recruited to fill the questionnaire as a control group. Cronbach's alpha, Pearson's correlation, and Interclass correlation were used to assess for internal consistency and reliability between test-retest of the Arabic version. RESULTS: The mean total score of DVSS for the case and control groups was 16.66 ± 6.07 and 6.11 ± 3.36, respectively (P < 0.001). The Arabic-DVSS showed excellent internal consistency (Cronbach's α > 0.9) for all the questions except Q1, Q3, Q6, and Q7 that showed good internal consistency. DISCUSSION: Translational and linguistic validation of the DVSS questionnaire into Arabic language is an important step toward its introduction in the clinical practice in Arabic countries; however, this step has also to consider the cultural variations between countries and not just linguistic translation. Generally, the Arabic-DVSS showed a satisfactory test-retest internal consistency and reliability with an excellent Cronbach's α (0.982) and ICC (0.962) for the total score of the Arabic-DVSS. Yet, the main limitation of this study was that it was only advocated for the translation and validation of the Arabic-DVSS and did not assess its value in patients' follow-up. CONCLUSION: The Arabic version of the DVSS is reliable and valid to help in the evaluation of DV in children of Arabic countries.

BACKGROUND: Ultrasound-guided Quadratus Lumborum block (QLB) is a regional analgesia approach that has been reported to provide effective post-operative pain relief for both abdominal and retroperitoneal surgery. Bupivacaine is the most often used and well documented local anesthetic medication in children. Dexamethasone is a systemic glucocorticoid that is often used to minimize postoperative nausea, vomiting, and pain to improve recovery quality after surgery. OBJECTIVES: To evaluate postoperative analgesia of QLB in pediatric patients undergoing renal surgeries by the addition of dexamethasone to bupivacaine compared to intravenous administration. STUDY DESIGN: A prospective, randomized, controlled clinical trial. SETTING: Pediatric surgery unit in a university hospital. METHODS: One hundred and five patients (6-12 years old) scheduled for renal surgeries were randomly allocated into 3 groups, with 35 patients in each group. Randomization was based on computer-generated codes. The groups were DEX1 (QLB with IV dexamethasone group), DEX2 (QLB dexamethasone group), and QLB CONTROL (QLB alone). The 1st time for rescue analgesia request, total morphine consumption, Pediatric Objective Pain Scale (POPS), and parents' satisfaction score were measured in 24 hours follow-up to evaluate postoperative pain control. RESULTS: The time to 1st rescue analgesics request (hours), total morphine consumption (mg), and the parents' satisfaction scores were much better in groups DEX1 and DEX2 as compared to group CONTROL with statistical significance. However, group DEX2 was better than DEX1 in the previous outcomes but without statistical significance. In respect, the pediatric objective pain scale was much lower with a significant difference in groups DEX1and DEX2 in comparison with group CONTROL up to 18 hours postoperatively. LIMITATIONS: Difficult to assess the block as all children were sedated, plus this was a unilateral surgical procedure with limited surgical incision, so the effect of QLB needed to be studied when there is a bilateral surgical procedure. CONCLUSIONS: Dexamethasone may be more effective when added to bupivacaine than when given systemically in analgesic effects without any impact on the other secondary pain-related outcomes. Dexamethasone as an adjuvant to bupivacaine has a marked hand on prolongation of the postoperative duration of analgesia, less request for rescue analgesia, and fewer side effects as compared to bupivacaine if used as a sole agent in QLB.

OBJECTIVES: To report on the live birth rates (LBRs) following percutaneous epididymal sperm aspiration (PESA) in men with obstructive azoospermia (OA) and factors affecting treatment outcome which is under reported in the literature. METHODS: This is a multicenter study that was conducted in Egypt including all couples undergoing intra cytoplasmic sperm injection (ICSI) for OA using PESA-derived sperms. Men were subdivided according to aetiology into congenital, iatrogenic and idiopathic groups. Fertilization, pregnancy and LBRs were determined and compared in each group. The longitudinal LBR, crude and expected cumulative delivery rates (CCDR, ECDR) were calculated. Multiple logistic regression analysis was used to determine signiï¬cant associations between maternal, paternal and ICSI factors with successful live births. RESULTS: Ninety couples were included in the study. Viable sperm for ICSI was retrieved in 89 men (98.9%). A total of 155 ICSI cycles with 17 frozen embryo transfers resulted in 81 pregnan-cies and 55 live births. After 5 cycles, the longitudinal LBR, CCDR and ECDR were 30%, 57.3% and 88.6% respectively. Maternal age and number of fertilized eggs were the only fac-tors signiï¬cantly affecting LBRs. CONCLUSIONS: PESA is a minimally invasive procedure for secur-ing viable sperm for ICSI in OA men, with high cumulative delivery rates. Maternal age and number of fertilized eggs are the only factors that signiï¬cantly affecting LBR. The contempo-rary longitudinal and cumulative LBRs provide objective out-come data to counsel OA patients undergoing fertility treat-ments.

OBJECTIVES: The aim of this study was to assess changes in quality of life and pain alleviation in women with refractory Interstitial Cystitis/Painful Bladder syndrome following a combined intravesical injection of Botulinum Toxin-A and Hyaluronic Acid instillation versus Hyaluronic acid instillation alone. METHODS: Two groups of women with painful bladder syndrome/interstitial cystitis were randomly divided (one to one randomization). Intravesical injections of botulinum toxin-A and intravesical Hyaluronic acid were given to Group (I). Only Hyaluronic acid was instilled intravesically in Group II. Patients were given voiding diaries, a visual analogue scale for pelvic pain, the International Cystitis Symptom Index and Problem Index, the Pelvic Pain Urgency/Frequency Patient Symptom Scale, and the Patient Health Questionnaire-9 to assess the candidates' quality of life. The Student t-test and mean and standard deviation were used in statistical analysis, with p 0.05 considered as significant (IBM SPSS statistics) Results: Thirty-four women were included in this study. The pain severity (VAS) of group (I) cases dropped dramatically from 8.5 ± 1.5 at the start to 3.9 ± 2.4 after three months and 2.9 ± 2.1 after six months. Among group (II) cases, the pain score reduced dramatically from 8.6 ± 1.3 to 5.8 ± 1.4 to 4.3 ± 2.6. CONCLUSIONS: In patients with refractory Interstitial Cystitis/Bladder Discomfort Syndrome, Botulinum Toxin-A injection combined with Hyaluronic Acid instillation improves pelvic pain and improves quality of life.

BACKGROUND & OBJECTIVE: Erectile dysfunction (ED) is one of the extrahepatic manifestations of hepatitis C virus infection that greatly affects patients' quality of life. Unfortunately, some of the drugs used for HCV treatment may have a negative impact on the patient's erectile function, such as the pegylated interferon. Currently, with the introduction of direct-acting antiviral drugs, there is scarce data in the literature about its potential impact on erectile function. In these settings, we aimed to assess the impact of sofosbuvir-based therapy on male erectile function. METHODS: This prospective interventional study was carried out in Benha University hospitals between January 2019 and May 2020. The study included all consecutive HCV patients with simultaneous ED coming to the hepatology outpatient clinic. Patients were divided into a study group who received sofosbuvir-based therapy (group A) or a control group who received silymarin therapy (group B). The International Index of Erectile Function-5 (IIEF-5) was used for the assessment of erectile function at different time points (pretreatment, 6 months, and 12 months after treatment). Different variables in both groups have been statistically analyzed. RESULTS: Overall, 75 patients who received sofosbuvir-based therapy and a control group (n = 35) matched for age and pretreatment variables (Child-Turcotte-Pugh score and Fibrosis-4 score). There was no significant difference between both groups in the pretreatment data. On the other hand, the posttreatment IIEF-5 was significantly higher in the sofosbuvir arm compared to the silymarin arm both at six months (p<0.001) and at 12 months (p<0.001). Furthermore, the age and the stage of liver fibrosis were negatively correlated with IIEF-5 at all-time points. CONCLUSION: The age and the stage of liver fibrosis are significantly correlated with the degree of ED. Furthermore, sofosbuvir-based therapy may be associated with significant improvement in patients with erectile function.

OBJECTIVE: To evaluate the impact of virtual reality on pain management during normal labor. METHODS: A systematic search was performed in September 2021 through PubMed, Cochrane Library, Scopus, and ISI web of science. We selected randomized clinical trials (RCTs) that compared virtual reality in the intervention group versus placebo or no intervention in the control group among laboring women during their normal delivery. Revman software was used for performing our meta-analysis. Our primary outcome was the pain score evaluated during the labor process by the Visual Analog Scale (VAS). Our secondary outcomes were anxiety and satisfaction scores during childbirth in addition to the duration of the first and second stages of labor. RESULTS: Eight RCTs met our inclusion criteria with a total number of 466 patients. We found virtual reality was linked to a significant reduction in the VAS pain score during labor compared to the control group (MD = -1.40, 95% CI [-1.83, -0.96], p < 0.001). The anxiety score during labor was significantly reduced among the virtual reality group (SMD = -1.15, 95% CI [-2.18, -0.12], p = 0.03). Moreover, virtual reality significantly improved the satisfaction score during labor (MD = 15.58, 95% CI [4.93, 26.22], p = 0.004). However, there were no significant differences between virtual reality and control groups regarding the duration of the first and second stages of labor. CONCLUSIONS: Virtual reality is an effective technique for reducing anxiety, increasing satisfaction, and improving pain management during normal labor.

BACKGROUND: The impact of warm ischemia time (WIT) on renal functional recovery remains controversial. We examined the length of WIT>30 min on the long-term renal function following on-clamp partial nephrectomy (PN). METHODS: Data from 23 centers for patients undergoing on-clamp PN between 2000 and 2018 were analyzed. We included patients with two kidneys, single tumor, cT1, minimum 1-year follow-up, and preoperative eGFR≥60 mL/min/1.73m2. Patients were divided into two groups according to WIT length: group I "WIT≤30 min" and group II "WIT>30 min." A propensity-score matched analysis (1:1 match) was performed to eliminate potential confounding factors between groups. We compared eGFR values, eGFR (%) preservation, eGFR decline, events of chronic kidney disease (CKD) upgrading, and CKD-free progression rates between both groups. Cox regression analysis evaluated WIT impact on upgrading of CKD stages. RESULTS: The primary cohort consisted of 3526 patients: group I (N.=2868) and group II (N.=658). After matching the final cohort consisted of 344 patients in each group. At last follow-up, there were no significant differences in median eGFR values at 1, 3, 5, and 10 years (P>0.05) between the matched groups. In addition, the median eGFR (%) preservation and absolute eGFR change were similar (89% in group I vs. 87% in group II, P=0.638) and (-10 in group I vs. -11 in group II, P=0.577), respectively. The 5 years new-onset CKD-free progression rates were comparable in the non-matched groups (79% in group I vs. 81% in group II, log-rank, P=0.763) and the matched groups (78.8% in group I vs. 76.3% in group II, log-rank, P=0.905). Univariable Cox regression analysis showed that WIT>30 min was not a predictor of overall CKD upgrading (HR:0.953, 95%CI 0.829-1.094, P=0.764) nor upgrading into CKD stage ≥III (HR:0.972, 95%CI 0.805-1.173, P=0.764). Retrospective design is a limitation of our study. CONCLUSIONS: Our analysis based on a large multicenter international cohort study suggests that WIT length during PN has no effect on the long-term renal function outcomes in patients having two kidneys and preoperative eGFR≥60 mL/min/1.73m2.

BACKGROUND: Suprapubic catheter migration to the vesicoureteral junction is an unusual complication, causing an obstruction that led to hydronephrosis and dilation of the pelvicalyceal system. Case presentation. A 30-year-old man with a suprapubic catheter (SPC) that was inserted one month before this current Emergency Department (ED) visit had severe left flank pain for 48 hours. The SPC was inserted in the context of urethral injury after falling astride. Point-of-Care Ultrasound (POCUS) showed a semifilled urinary bladder and moderate hydronephrosis on the left side. A computed tomography scan (CT scan) of the abdomen was performed and showed migration of the suprapubic catheter's tip into the left vesicoureteral junction, causing ureteral obstruction dilation of the ipsilateral pelvicalyceal system. The suprapubic catheter was changed in the ED, causing relief of symptoms, and the patient was referred to the urology department for follow-up. It was uneventful on the follow-up from the SPC clinic. CONCLUSIONS: This case report describes a rare complication of migration of the suprapubic catheter to the vesicoureteral junction causing acute ureteral obstruction and hydronephrosis.
RESUMO
INTRODUCTION: We evaluated the efficacy and safety of laparoscopic ureterolithotomy (LPU) for the treatment of large proximal ureteric stone. METHODS: A retrospective multicenter analysis for patients with solitary impacted proximal ureteric stone ≥15 mm who underwent LPU from 2016 to 2019 was performed. Primary outcome was to estimate the stone-free rate (SFR). SFR was defined as absence of residual stones on postoperative computed tomography scan. Secondary outcome was to assess the perioperative outcomes, as well as to review literature data of randomized controlled trials and meta-analyses comparing LPU to other treatment options. RESULTS: Forty-four patients were included in our study. Mean stone size was 22.9 ± 5.8 mm and median follow-up was 14 months. Three patients had previous abdominal surgery, one patient had severe degree of scoliosis and six patients failed primary therapy. All stones were extracted successfully (SFR = 100%) without need of auxiliary treatments. Mean operative time and estimated blood loss were 86.6 ± 14.1 minutes. and 11.9 ± 14.7 mL, respectively. No intraoperative complications or conversion to open surgery were reported. No major postoperative complications (≥grade 3) were reported. Mean length of hospital stay was 2 ± 0.8 days. CONCLUSIONS: For treatment of large ureteric stones, our study showed that LPU achieves 100% stone-free status. When performed by well-trained laparoscopic surgeons, it is safe and has no major perioperative complications. According to our results and literature data, when counseling patients with large impacted proximal ureteral stones, LPU should be advised as the procedure that has the higher SFR, lower auxiliary treatments, and comparable complication rates to other treatments.

BACKGROUND: The aim of the present study was to compare the surgical outcomes of retzius-sparing robot-assisted radical prostatectomy (RS-RARP) and open retropubic radical prostatectomy (ORP). METHODS: We included patients with clinically localized prostate cancer who underwent RS-RARP or ORP and met our inclusion criteria. We compared the perioperative, oncological, and continence outcomes between both surgical approaches. Continence function was assessed using the validated International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form. Continence was defined as using 0-1 safety pad per day. Biochemical recurrence (BCR) was defined as two consecutive rises in serum PSA more than 0.2 ng/mL. Events of local recurrence, distant metastasis, and cancer death were reported and compared using Kaplan-Meier survival analysis. RESULTS: Between 1 June 2013 and 1 October 1 2016, 184 men were enrolled, of whom 125 underwent RS-RARP and 59 underwent ORP. Baseline demographic and pathological characteristics were similar between both groups (P>0.05). Patients in RS-RARP group had significantly lower blood loss, fewer transfusion rates, lower VAS score, and shorter hospital stay than patients in ORP group (P<0.05). Major complications (≥grade 3b) did not differ between both groups (P=0.121). Positive surgical margins were 28.8% and 24.8% in ORP and RS-RARP, respectively (P=0.494). The BCR free-survival rates in ORP and RS-RARP at 1-year was 87.3% and 92.3%, respectively (Log-rank, P=0.740). At 1-, 6-, and 12-month after surgery, 42.4%, 79.7%, and 84.7% of men undergoing ORP were continent, compared with 72.8%, 90.4%, and 92% undergoing RS-RARP, respectively. Men in RS-RARP group achieved faster recovery of urinary continence compared to men in ORP group (Log-rank, P=0.001). CONCLUSIONS: RS-RARP had better perioperative outcomes and faster recovery of urinary continence compared with ORP. Short-term oncological outcomes were comparable between both surgical approaches.
