The effect of transobturator tape surgery on female sexual function: a systematic review and meta-analysis.

PURPOSE: We aimed to review the literature regarding the effects of trans obturator tape surgery (TOT) on sexual functions in women with stress urinary incontinence (SUI) to reveal compact data and to reach more consistent and reliable results. METHODS: PRISMA statement was used in the current review. The databases of PubMed (Medline), Science Direct, and Cochrane Central Register of Controlled Trials were detected independently. We evaluated the studies comparing the preoperative and postoperative sexuality parameters related to the TOT procedure in females. Studies presenting the mean and standard deviation(SD) of global and sub-item Female Sexual Function Index(FSFI) were included in the current study. RESULTS: We identified 783 studies in full publications or abstract forms using the methodology above and the search terms. Finally, eight studies were included in the meta-analysis. The pooled analysis of the mean difference demonstrated that the total sexual function scores of the patients improved after TOT surgery. CONCLUSION: The data collected from the current meta-analysis suggest that TOT surgery improves female sexual function.

Factors predicting the need for surgical intervention for hydronephrosis during pregnancy: a systematic review of the literature.

PURPOSE: Symptomatic hydronephrosis in pregnancy can cause both maternal and obstetric complications. In various studies, factors predicting the need for surgical intervention have been evaluated, however these factors have not been systematically assessed yet. This systematic review analyzes published studies about hydronephrosis during pregnancy and determines the predictive factors for the need for surgical intervention for hydronephrosis during pregnancy. MATERIALS AND METHODS: A systematic review was conducted in January 2023 using the Medline, Web of Science and ScienceDirect/Scopus databases according to PRISMA guidelines. We searched these databases with the following search strategy: (intervention OR nephrostomy OR stent insertion) AND (pregnancy hydronephrosis). RESULTS: The literature review revealed 2461 potentially eligible studies. After the screening, six studies were enrolled in this review. High neutrophil-to-lymphocyte ratio, high C-reactive protein level, high white blood cell count, high creatinine levels, fever, persistent pain for more than 4 days, presence of ureteral stones more than 8 mm, high grade hydronephrosis, high fetal body weight and high delta resistive index were reported to be related with the need for surgical intervention. CONCLUSION: The rate of symptomatic hydronephrosis and requirement for surgical intervention is low during pregnancy. However, as symptomatic hydronephrosis may cause serious obstetric complications, it is important to know the parameters that can predict patients who may need surgical intervention. These results will assist gynecologists and urologists to stratify pregnant women for surgical intervention.

Comparison of Health-Related Quality of Life Changes in Prostate Cancer Patients Undergoing Laparoscopic versus Robotic-Assisted Laparoscopic Radical Prostatectomy: A Systematic review.

PURPOSE: To compare the effects of RALP and LRP on health-related QoL following radical prostatectomy, focusing on studies performed via validated QoL questionnaires measuring particularly general health-related QoL. MATERIAL AND METHODS: A systematic search was conducted using Web of Science, PubMed (MEDLINE) on 15 January 2023 with the following search terms solely or in combination: "robotic radical prostatectomy", "laparoscopic radical prostatectomy," and "quality of life". After retrieving the titles and abstracts of selected articles, the full texts of related articles were screened. RESULTS: After full-text evaluation, among 185 articles, 23 articles were found eligible for inclusion. Hoze et al. reported that the global health status at the 12th month of the surgery was almost the same in both groups according to EORTC- QLQ-C30 scores (76.3 in the RALRP group vs. 76.1 in the LRP group). Wang et al. reported a 75 point of EORTC-QOL-C30 global health status ten years after LRP. Wyler et al. found that the 1-3 month EORTC-QLQ-C30 global health score was significantly worser than the baseline score, 65.3±18.3 vs. 77.2±18.2; however, it returned to baseline in 13-24 months (77.7±16.8) even proceed baseline score in experienced hands at 49-58 months follow up, 78.2±17.8 vs. 85.3±15.5. The frequently used patient-reported quality of life questionnaire following RALRP was EORTC-QLQ. CONCLUSION: Both robotic-assisted and laparoscopic radical prostatectomy are valid treatment options to achieve a good quality of life following surgery. The intermediate and long-term results in regard to QoL are comparable between the two procedures. RALRP might be superior to LRP in terms of immediate health-related quality of life, which might contribute to early recovery of urinary function.

Worldwide trends of practice and intervention in paediatric endourology: comparison of European versus Non-European responses.

Introduction: The area of paediatric endourology is unique and is recognised to be challenging, and it requires a certain level of focused training and expertise. Our aim was to conduct a worldwide survey in order to gain an overview regarding the current practice patterns for minimally invasive treatments of paediatric upper urinary tract stone patients. Material and methods: The survey was distributed between December 2021 and April 2022 through urology sections and societies in United Kingdom, Latin America and Asia. The survey was made up of 20 questions and it was distributed online using the free online Google Forms (TM). Results: 221 urologists answered the survey with 56 responses each from India, South America and UK and 53 responses from the rest of Europe (15 countries). In total, 163 responders (73.7%) managed paediatric stone patients in their daily practice. Of the responders, 60.2% were adult urologists and 39.8% were paediatric urologists. 12.9% adult urologists and 20.4% paediatric urologists run independent clinics while some run combined adult and paediatric clinics sometimes with the support of the nephrologists. Only 33.9% urologists offered all surgical treatments [extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL), ureteroscopy (URS) and retrograde intrarenal surgery (RIRS)]. Conclusions: Treatment of paediatric stones can vary according to country and legislations. Based on the results of this survey, minimally invasive methods such as URS and mini PCNL seem to have become more popular. In most institutions a collaboration exists between adult and paediatric urologists, which is the key for a tailored decision making, counselling and treatment success.

Surgical techniques to preserve continence after robot-assisted radical prostatectomy.

Radical prostatectomy significantly impacts the inherent anatomy of the male pelvis and the functional mechanisms of urinary continence. Incontinence has a considerable negative influence on the quality of life of patients, as well as their social and psychological wellbeing. Numerous surgical techniques have been demonstrated to support the preservation of continence during robot-assisted radical prostatectomy (RARP). In this in-depth analysis, we give a general summary of the surgical techniques used in RARP and their impact on incontinence rates.

The heat is on: the impact of excessive temperature increments on complications of laser treatment for ureteral and renal stones.

OBJECTIVE: Technological advancements in the field of urology have led to a paradigm shift in the management of urolithiasis towards minimally invasive endourological interventions, namely ureteroscopy and percutaneous nephrolithotomy. However, concerns regarding the potential for thermal injury during laser lithotripsy have arisen, as studies have indicated that the threshold for cellular thermal injury (43 °C) can be exceeded, even with conventional low-power laser settings. This review aims to identify the factors that contribute to temperature increments during laser treatment using current laser systems and evaluate their impact on patient outcomes. MATERIALS AND METHODS: To select studies for inclusion, a search was performed on online databases including PubMed and Google Scholar. Keywords such as 'temperature' or 'heat' were combined with 'lithotripsy', 'nephrolithotomy', 'ureteroscopy', or 'retrograde intrarenal surgery', both individually and in various combinations. RESULTS: Various strategies have been proposed to mitigate temperature rise, such as reducing laser energy or frequency, shortening the duration of laser activation, increasing the irrigation fluid flow rate, and using room temperature or chilled water for irrigation. It is important to note that higher irrigation fluid flow rates should be approached cautiously due to potential increases in intrarenal pressure and associated infectious complications. The utilization of a ureteral access sheath (UAS) may offer benefits by facilitating irrigation fluid outflow, thereby reducing intrapelvic pressure and intrarenal fluid temperature. CONCLUSION: Achieving a balance between laser power, duration of laser activation, and irrigation fluid rate and temperature appears to be crucial for urologists to minimize excessive temperature rise.

The Prime Time for Flexible Ureteroscopy for Large Renal Stones Is Coming: Is Percutaneous Nephrolithotomy No Longer Needed?

Advances in laser technology and surgical telescopic systems have propelled retrograde intrarenal surgery (RIRS) to the forefront as a viable alternative to percutaneous nephrolithotomy (PCNL). Currently, RIRS is being increasingly utilized as a treatment option, even for kidney stones larger than 2 cm. In this narrative review, we aimed to take a snapshot of current practice in renal stone treatment and the latest technological and technical developments and to evaluate the efficacy of RIRS in larger renal stones. With low complication rates and acceptable stone-free rates, RIRS offers patients a less invasive option with favorable outcomes. There are insufficient data comparing PCNL with RIRS using a new-generation high-power laser and suctioning ureteral access sheath (UAS). Further studies with novel lasers and UAS could provide superiority in terms of RIRS. It is crucial to take into account various patient-specific considerations, such as stone location and burden, when deciding on the appropriate treatment approach.

Is day-case surgery feasible for laser endoscopic enucleation of the prostate? A systematic review.

PURPOSE: Laser endoscopic enucleation of the prostate (EEP) for benign prostatic obstruction has become increasingly prevalent worldwide. Considering the medical cost-savings and concomitantly fewer nosocomial infections, the feasibility of same-day postoperative discharge of patients who have undergone laser EEP in terms of its safety and effectiveness has become a subject matter of growing interest. We aimed to review those studies focussing on day-case surgery (DCS) in patients undergoing laser EEP. METHODS: A systematic search was conducted using PubMed-MEDLINE and Web of Science databases until October 2022 with the following search terms: "same day discharge AND laser enucleation of the prostate", "day-case AND laser enucleation of the prostate", "same day surgery AND laser enucleation of the prostate" and "one day surgery AND laser enucleation of the prostate" by combining PICO (population, intervention, comparison, outcome) terms. We identified 15 eligible studies. RESULTS: While 14 of the studies focussed on holmium laser EEP, one focused on thulium laser vapoenucleation of the prostate. We observed an improvement in functional parameters in all studies we reviewed, and DCS success and readmission rates ranged between 35.3-100% and 0-17.8%, respectively. The complication rates varied between 0 and 36.7%, most of the complicatons were Clavien-Dindo (CD) I and II. CD ≥ III complications did not significantly differ between same day discharge (SDD) and non-SDD groups in the studies. CONCLUSION: Laser EEP is feasible and promising DCS treatment option delivering improved functional parameters compared to baseline values, and lower perioperative complication and readmission rates in certain patients.

Estimated Radiation Dose to the Lens During Endourologic Procedures: The Role of Leaded Glasses and the ALARA Protocol-An ESU/ESUT-YAU Endourology Group Collaboration.

Purpose: On February 6, 2018, the European Atomic Energy Community reduced the annual equivalent dose limit for the lens from 150 to 20 mSv/year, because of its association with cataracts at low radiation doses. Our aim was to estimate the radiation doses received by the lens during endourologic procedures that require fluoroscopy. Materials and Methods: Multicenter study including prospective data of annual eye dosimeters between 2017 and 2020. Four endourologists used an eye dosimeter in endourologic procedures that require fluoroscopy (ureteroscopy, retrograde intrarenal surgery, and percutaneous nephrolithotomy). Surgeons 1 and 2 wore leaded glasses; surgeon 1 also used the as low as reasonably achievable (ALARA) protocol. Descriptive statistical analysis using SPSS 25.0 was conducted. Results: Surgeons 1, 2, 3, and 4 performed a median of 159, 586, 102, and 129 endourologic procedures per year, respectively, for a total of 641, 2340, 413, and 350 procedures between 2017 and 2020. The median annual dose of lens radiation exposure was 0.16, 1.18, 3.79, and 1.42 mSv per year, respectively, which corresponds to 0.001, 0.009, 0.024, and 0.012 mSv per procedure. The two surgeons who used leaded glasses registered a lower radiation dose per procedure (0.001 vs 0.027). Similarly, the urologist who used the ALARA protocol registered the lowest lens radiation dose compared with the three surgeons who did not use it (0.001 vs 0.023). Conclusions: The endourologists who participated in this study effectively comply with current guidelines on radiation exposure to the lens. Registered eye lens radiation does not seem to be related to the number of procedures but rather to the use of leaded glasses and the ALARA protocol.

Predictors of Ureteral Strictures after Retrograde Ureteroscopic Treatment of Impacted Ureteral Stones: A Systematic Literature Review.

BACKGROUND: The stricture-formation rate following ureteroscopy ranges from 0.5 to 5% and might amount to 24% in patients with impacted ureteral stones. The pathogenesis of ureteral stricture formation is not yet fully understood. It is likely that the patient and stone characteristics, as well as intervention factors, play a role in this process. In this systematic review, we aimed to determine the potential factors responsible for ureteral stricture formation in patients having impacted ureteral stones. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) criteria, we conducted systematic online research through PubMed and Web of Science without a time restriction, applying the keywords "ureteral stone", "ureteral calculus", "impacted stone", "ureteral stenosis", "ureteroscopic lithotripsy", "impacted calculus", and "ureteral strictures" singly or in combination. RESULTS: After eliminating non-eligible studies, we identified five articles on ureteral stricture formation following treatment of impacted ureteral stones. Ureteral perforation and/or mucosal damage appeared as key predictors of ureteral stricture following retrograde ureteroscopy (URS) for impacted ureteral stones. Besides ureteral perforation stone size, embedded stone fragments into the ureter during lithotripsy, failed URS, degree of hydronephrosis, nephrostomy tube or double-J stent (DJS)/ureter catheter insertion were also suggested factors leading to ureteral strictures. CONCLUSION: Ureteral perforation during surgery might be considered the main risk factor for ureteral stricture formation following retrograde ureteroscopic stone removal for impacted ureteral stones.

How to Deal With Hemophilia C in Endoscopic Urologic Surgery: Lessons Learned From a Transurethral Resection of Bladder Tumor Case.

Factor XI deficiency (hemophilia C or Rosenthal syndrome) is an inherited rare disorder that leads to abnormal bleeding due to the paucity of the protein named factor XI, which plays a role in the blood clotting cascade. A 42-year-old male was referred to the urology outpatient clinic with macroscopic hematuria. The patient was scheduled for a repeat transurethral resection of a bladder tumor (TURBT). Preoperative coagulation parameters were as follows: the international normalized ratio (INR) was 0.95 (0.85-1.2), the prothrombin time was 10.9 seconds (10-15), and the partial thromboplastin time was 43.7 seconds (21-36). On the second postoperative day, he developed pelvic pain and discomfort. An abdominal CT revealed a 10 cm mass consistent with clot retention. The patient received two units of erythrocyte suspension and six units of fresh frozen plasma to prevent the depletion of hemoglobin and control urinary bleeding. The patient was discharged with a good recovery from the hospital three days after the second surgery. Hematologic disorders are rare but might have fatal consequences following surgery if unnoticed at the earliest stage. Clinicians must consider that patients with a history of unusual bleeding or borderline coagulation parameters might have an underlying hematological disorder and perform a further evaluation.

Definition of clinically insignificant residual fragments after percutaneous nephrolithotomy among urologists: a world-wide survey by EAU-YAU Endourology and Urolithiasis Working Group.

Introduction: The aim of this article was to evaluate the current perception of urologists as to what size is considered as a clinically insignificant residual fragment (CIRF). Material and methods: A survey was globally distributed to the members of the Endourological Society via SurveyMonkey. Results: A total of 385 participants responded to the survey on CIRF. Most participants considered 2 mm (29%) as CIRF threshold, followed by 3 mm (24%), 4 mm (22%), 0 mm (14%), 5 mm (8%) and 1 mm (3%). North American urologists considered CIRF to be smaller than urologists from Asia, Eurasia and South America, (p-values ≤0.001, 0.037 and 0.015 respectively). European urologists identified smaller CIRF in comparison to Asian urologists (p-value = 0.001). Urologists mainly using a pneumatic lithotripter accepted larger fragments as CIRF, compared to urologists mainly using ultrasonic devices or a combination of ultrasonic and pneumatic devices (p-value = 0.026 and 0.005 respectively). Similarly, urologists mainly performing X-Ray and ultrasound as post-operative imaging accepted larger fragments as CIRF in comparison to urologists mainly performing non-contrast computed tomography (p-value = 0.001). Conclusions: What is considered as CIRF varies between urologist from different continents and seems to be associated with the lithotripter used and the post-operative imaging modality of preference to assess treatment success.

Laser enucleation of the prostate in men with very large glands ≥175 ml: A systematic review.

Background: Surgical treatment options for lower urinary tract symptoms can differ according to prostate size. There are few studies on the efficacy and safety of endoscopic enucleation of prostate (EEP) in patients with very large prostates focusing on laser as energy source. In this systematic review, we aimed to examine the efficacy and safety of laser-based EEP on prostate glands ≥150 ml. Methods: A systematic search was conducted using Web of Science, PubMed-MEDLINE, Wiley Online Library and Cochrane Library databases with the following search terms solely or in combination: "large prostate", "laser enucleation", "laser prostatectomy"by combining PICO (population, intervention, comparison, and outcome) terms. Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines were followed. Results: We retrieved 6 studies included 375 patients with prostate sizes ≥175 ml treated with laser-based EEP for symptomatic benign prostatic obstruction. Three studies examined Holmium laser enucleation of prostate (HoLEP) outcomes with a prostate volume (PV) >200 ml, one evaluated HoLEP outcomes with a PV of 200-299 and ≥ 300 ml, two studies evaluated HoLEP outcomes with a PV > 175 ml. We observed improvement in postoperative functional outcomes in patients with a PV > 175, >200 and >300 ml. The retreatment rate was 0-1.3% in all studies involving prostate size ≥175 ml. Most of the complications were Clavien-Dindo I (%0-9) and II (%12.7-16.6). Conclusions: Laser-based EEP is an efficient, safe and feasible procedure even in very large prostates with good functional outcomes, low perioperative complication and retreatment rates.

Worldwide practice patterns of percutaneous nephrolithotomy.

PURPOSE: To evaluate the current practice of percutaneous nephrolithotomy (PCNL), conducting a worldwide survey among urologists with a special interest in endo-urology. METHODS: A 22-question survey was specifically developed by the European Association of Urology (EAU) young academic urologists (YAU) and uro-technology (ESUT) groups and globally distributed via SurveyMonkey to almost 2000 members of Endourology Society. The questionnaire included questions dedicated to the demographics and general practice of the participating urologists. RESULTS: In total, 441 responses (male/female ratio - 418/23) were received. A comparatively higher percentage of specialists (56.2%) practiced in academic institutions and had specific endo-urological fellowship training (56.7%). The classical prone PCNL remained the most practiced approach among the surveyed specialists, 47.7% stated to always do prone PCNLs, while 51.8% of respondents used multiple positioning options as required. The PCNL tract was mostly performed by urologists (84.3%) and fluoroscopic guidance was still predominantly used by 74.5% of respondents. The most practiced tract dilation method was balloon dilator used by 42% of respondents. Most of the surveyed urologists had ultrasonic, pneumatic or laser lithotripsy devices in their armamentarium. The use of some form of post-procedural drainage was reported in 85.1% of respondents, whereas tubeless PCNL remained a fairly uncommon practice. CONCLUSION: The majority of urologists still use prone positioning, get their own access under fluoroscopy guidance and use a balloon for tract dilation. However, we also identified that when necessary, urologists will deviate from routine practice and change strategy, adopting other approaches for PCNL.
