RESUMEN

Prostate cancer is the second most common cancer among men, with many treatment modalities available for patients, such as radical prostatectomy, external beam radiotherapy, brachytherapy, high-intensity focused ultrasound, cryotherapy, electroporation and other whole-gland or focal ablative novel techniques. Unfortunately, up to 60% of men with prostate cancer experience recurrence at 5 to 10 years. Salvage radical prostatectomy can be offered as an option in the setting of recurrence after a primary non-surgical treatment. However, the complexity of salvage radical prostatectomy is considered to be greater than that of primary surgery, making it the least popular treatment of choice. With the wide use of robotic platforms in urologic oncologic surgery, salvage radical prostatectomy has attracted attention again because, compared to past data, modern series involving salvage Robot-Assisted Radical Prostatectomy have shown promising results. In this narrative literature review, we comprehensively examined data on salvage radical prostatectomy. We investigated the correlation between the different types of primary prostate cancer therapy and the following salvage radical prostatectomy. Furthermore, we explored the concept of a robotic approach and its beneficial effect in salvage surgery. Lastly, we emphasized several promising avenues for future research in this field.

RESUMEN

PURPOSE: The recent discovery of the urinary microbiome has led to an emerging field of investigation about the potential role of microorganisms in the pathogenesis of urinary bladder cancer. Few preliminary data have been reported so far implicating urobiome as causative and prognostic factor of bladder tumorigenesis. In the present study, a review of the current evidence is presented about microbiome composition among patients with bladder cancer and healthy individuals as well as possible implications of microbiome on urothelial carcinoma of the bladder. METHODS: A literature review was conducted using PubMed/MEDLINE, Scopus, and the Cochrane library until December 2023. Search algorithm was constructed using the following terms and their associated Mesh terms and Boolean operators: "urinary microbiome" and "urinary microbiota". Studies written in English language, identifying, and comparing urinary microbiome among bladder cancer patients and healthy control group were included in the review. RESULTS: A total of 2,356 reports were identified. From this total 16 articles complied with the inclusion criteria were selected for analysis. These articles represent a total of about 486 bladder cancer patients. CONCLUSION: Recent studies revealed the colonization of the urinary tract and the bladder by micro-organisms using both enhanced culture- and molecular-based techniques for microbial characterization. However, several limitations exist in the literature decreasing the reliability of the current reports. As a result, urinary microbiome consist an ambitious era in bladder cancer research with an increasing number of evidence about its potential pathogenetic, prognostic and therapeutic role.

RESUMEN

With the rapid increase in computer processing capacity over the past two decades, machine learning techniques have been applied in many sectors of daily life. Machine learning in therapeutic settings is also gaining popularity. We analysed current studies on machine learning in robotic urologic surgery. We searched PubMed/Medline and Google Scholar up to December 2023. Search terms included "urologic surgery", "artificial intelligence", "machine learning", "neural network", "automation", and "robotic surgery". Automatic preoperative imaging, intraoperative anatomy matching, and bleeding prediction has been a major focus. Early artificial intelligence (AI) therapeutic outcomes are promising. Robot-assisted surgery provides precise telemetry data and a cutting-edge viewing console to analyse and improve AI integration in surgery. Machine learning enhances surgical skill feedback, procedure effectiveness, surgical guidance, and postoperative prediction. Tension-sensors on robotic arms and augmented reality can improve surgery. This provides real-time organ motion monitoring, improving precision and accuracy. As datasets develop and electronic health records are used more and more, these technologies will become more effective and useful. AI in robotic surgery is intended to improve surgical training and experience. Both seek precision to improve surgical care. AI in ''master-slave'' robotic surgery offers the detailed, step-by-step examination of autonomous robotic treatments.

RESUMEN

Current management of non-metastatic muscle invasive bladder cancer (MIBC) includes radical cystectomy and cisplatin-based neoadjuvant chemotherapy (NAC), offers a 5-year survival rate of approximately 50% and is associated with significant toxicities. A growing body of evidence supports the role of liquid biopsies including circulating tumour DNA (ctDNA) as a prognostic and predictive marker that could stratify patients according to individualised risk of progression/recurrence. Detectable ctDNA levels prior to radical cystectomy have been shown to be correlated with higher risk of recurrence and worse overall prognosis after cystectomy. In addition, ctDNA status after NAC/neoadjuvant immunotherapy is predictive of the pathological response to these treatments, with persistently detectable ctDNA being associated with residual bladder tumour at cystectomy. Finally, detectable ctDNA levels post-cystectomy have been associated with disease relapse and worse disease-free (DFS) and overall survival (OS) and might identify a population with survival benefit from adjuvant immunotherapy.

RESUMEN

BACKGROUND: In urology, ureteral stents are used to treat obstructive diseases. Hematuria (54%), fever, discomfort, and lower urinary system symptoms are the predominant symptoms related to ureteral stent. AIM: This article links stent symptoms to double-j width and length, as well as patient's height, weight, and body mass index (BMI). Ureteric Stent Symptoms Questionnaire (USSQ) was used to measure ureteral stent symptoms at 1st and 4th week of stent in situ as well as the 4th week after pigtail removal. METHODS: A 200-patient prospective study, where patients were allocated into four groups following ureteral stent insertion depending on the stent characteristics. Those groups were: 4.8 Fr./26 cm (Group A), 4.8 Fr./28 cm (Group B), 6 Fr/26 cm (Group C), and 6 Fr/28 cm (Group D). RESULTS: Men comprised 53.5% of 200 patients. Participants had an average age of 49 ± 15.5 years, height of 175 ± 8.94 cm, and BMI of 23.8 ± 7.6 cm. The laboratory results were identical between groups. At the first and fourth week, groups had similar urine symptoms, pain severity, health status and occupational activities. The difference in pain location was statistically significant. Group A had 82.4% renal back pain in the first week, whereas Group B had 68.8%, Group C 31.3% and Group D 62.5 (p=0.04). At the fourth week, 64.7% of Group A patients reported kidney front pain, compared to 100% of Group B, 93.3% of Group C, and 100% of Group D (p=0.04). There was statistical significance in the sexual activity of the patients. 24.4% of Group C patients stopped sexual activity before stent installation, compared to 10.6%, 8.3%, and 6.4% of the other groups (p=0.03). A moderate percentage of patients had active sexual activity at week 4 (Group A: 7.8%, Group B: 5.8%, Group C: 8.2%, Group D: 4.1%), p=0.83. In multivariate analysis, urinary catheter group, age, weight, height, and BMI did not significantly affect urine index score (UIS), pain index score (PIS), general health (GH), quality of work (QW), and quality of sex (QS). CONCLUSIONS: Despite various attempts to establish the best ureteral stent, the effect of double-j stent physical features on stent-related symptoms remained unknown. No verdict is conceivable without adequate empirical data.

RESUMEN

Background: In routine urological practice, pigtails are frequently utilized to relieve blockage. Early signs of pigtail problems include pain, lower urinary tract symptoms, pain, hematuria (54%) and fever. Seventy percent of patients experience irritable voiding symptoms, and 80% of patients or even more report pain interfering with everyday activities. Methods: This article's goal is to evaluate the various polymeric stents that are currently on the market. In addition, a review of their fundamental bioqualities is conducted, and a connection between their physical attributes (length, size, and composition) and stent-related issues is looked into. For this review, extensive Medline, PubMed, and literature research from 1987 to January 2023 was conducted. Lower urinary tract complaints, ureteral stents, "pigtail," "materials," "characteristics," or "properties" were the search terms employed. Results: The reviews and publications that are now accessible linking certain materials to stent-related symptoms offer contradictory conclusions, and the majority of research do not specify the precise properties of the materials utilized. The results of the studies on the relationship between stents length and diameter and symptoms connected to stents are likewise inconclusive, despite the fact that there are several studies on this topic in the literature. Conclusion: Numerous studies imply a connection between the various types and properties of the utilized stents and stent-related complaints. However, the available data did not fully support this claim, necessitating additional research.

RESUMEN

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.

RESUMEN

INTRODUCTION: Prostate cancer is the most common malignancy in the male. Androgen-deprivation therapy (ADT) has been the mainstay in the treatment of metastatic prostate cancer however, due to the outgrowth of castration-resistant cell population the disease inevitably progresses to an aggressive, difficult to handle stage. AREAS COVERED: We have reviewed the literature regarding hormonal-directed therapy prostate cancer. New agents, namely abiraterone acetate, combined with prednisone, and next generation antiandrogens (enzalutamide, apalutamide and darolutamide) have shown considerable efficacy, not only in patients with metastatic but also in those with non-metastatic disease, either castration resistant (CRPC) or hormone sensitive (HSPC). EXPERT OPINION: The addition of abiraterone and of the second-generation antiandrogens to our therapeutic armamentarium has improved prognosis ofprostate cancer in the last decade. Abiraterone is a viable option in patients with metastatic disease (hormone-sensitive and castration-resistant), whereas all next-generation antiandrogens have demonstrated efficacy in terms of metastasis-free and overall survival in non-metastatic CRPC. In addition, enzalutamide has also been found efficacious in mCRPC and mHSPC, while apalutamide in mHSPC. Currently there are no reliable data to indicate a potential superiority of one of these agents over the others in CRPC or HSPC as there are no relevant head to head studies . Sequencing hormone treatment modalities, chemotherapies and immunotherapies have not reached a consensus as yet. Randomized controlled trials are warranted to clearly define the role of novel antiandrogens in the treatment of prostate cancer. The choice of treatment should be individualized following discussion with the patient .

RESUMEN

The purpose of this article is to review the effects of different types of pharmacotherapy on symptoms that affect the quality of a patient's life after stent insertion. A thorough Medline/PubMed nonsystematic review was conducted from 1987 to January 2023, using the terms: "pigtail" OR "ureteral stents" AND "lower urinary tracts symptoms" OR "LUTS" AND "pharmacotherapy" OR "drugs". Relevant studies conducted in humans and reported in English language were included. The available reviews and articles associating the use of drugs with stent-related symptoms (SRS) provide conflicting results. Most of them show a clear benefit of alpha blockers, particularly alfuzosin, on treating urinary SRS, and hence there is a strong recommendation for the use of alpha blockers for the treatment of SRS in the guidelines of the European Association of Urology. Anticholinergics and mirabegron have shown a significant benefit in dealing with irritative bladder symptoms. In contrast, the findings for combination therapies are contradictory, with some studies showing that combination therapy is no superior to monotherapy with regards to most of the subsets of the Ureteral Stent Symptom Questionnaire (USSQ), whereas others present a clear benefit of combination therapies, specifically silodosin and solifenacin, in treating stent-associated lower urinary tract symptoms (LUTS), in comparison with any other type of monotherapy or combination therapy. Many studies suggest that some categories of pharmacotherapy, such as alpha blockers, can alleviate SRS. However, there is conflicting evidence concerning most other types of medical treatment. Randomized trials with the largest number of patients are needed to investigate the effectiveness of novel approaches on SRS.

RESUMEN

INTRODUCTION: This study aims to determine the effects of radical retropubic prostatectomy on post-operative erectile function. MATERIALS & METHODS: A total of 50 patients were included in this study, diagnosed with localized prostate cancer, and underwent nerve-sparing radical retropubic prostatectomy. All patients completed the International Index of Erectile Function (IIEF-5) questionnaire pre-operatively and on the third, sixth, and twelfth post-operative month and completed a self-reporting of their satisfaction with their sexual performance. Patients with a history of severe heart disease, were on erectile dysfunction medication, or had a score of 7 or less on the IIEF-5 questionnaire, were excluded from the study. RESULTS: Pre-operatively it was observed that the lower the IIEF-5 score, the higher the biopsy Gleason score. Post-operatively, 16 patients stated that erectile function had returned to the pre-operative IIEF-5 category. In contrast, only 13 of them stated they were happy with their sexual performance on the self-reporting scale. The rest reported dissatisfaction despite returning to their pre-operative erectile function status. IIEF-5 scores were also different when compared amongst the four age groups, with scores indicating that younger age is related to higher IIEF-5 scores. At the 3-month follow-up, no statistically significant difference was observed between age groups. Finally, patients younger than 64 reported significantly less deterioration in post-operative erectile function. CONCLUSION: Post-radical prostatectomy erectile dysfunction remains one of the most pressing issues in prostate cancer therapy. A higher Gleason score has a more significant impact on pre-operative ED, and at the same time, the best post-operative ED results are observed in younger patients. Finally, patients need extensive follow-up, therapy, and pre-and post-operative psychological support to have the best possible erectile function.

RESUMEN

BACKGROUND: Risk factors like smoking, radiation, chronic infections and exposure to occupational chemicals are strongly associated with occurrence of bladder cancer. Association between increased body weight and bladder cancer has been controversial. The aim of this case-control study is to evaluate association of anthropometric characteristics on bladder cancer incidence in Greek population. METHODS: This case-control study was conducted at a tertiary hospital in Greece with cases being patients with bladder cancer diagnosed within the last 2 years and controls patients admitted to hospital for reason other than cancer and not related to common risk factors related to bladder cancer. Anthropometric characteristics like weight, height, body mass index, waist and hip circumference were measured. Analyses was done with R (Vienna, Austria). RESULTS: Comparison between groups showed that patients with bladder cancer had higher weight, BMI and waist circumference compared to controls. However, multivariate, binomial logistic regression showed that only age (OR 1.03, 95% CI: 1-1.05, p = 0.02), no use of smoke (OR 0.12, 95% CI: 0.07-0.23, p < 0.001) and occupation related to bladder cancer (OR 7.45, 95% CI: 2.53-27.93, p < 0.001) significantly predicted the incidence of bladder cancer. CONCLUSIONS: Bladder cancer incidence is strongly linked with specific risk factors such as smoking, occupation with exposure to chemicals and smoke, increasing age, radiation and chronic infections. Several studies have shown a weak association between anthropometric characteristics and bladder cancer, although most studies in European populations did not confirm these findings. Similarly in our case-control study in a Greek population, we found potential relationship between increased weight/BMI and waist circumference with bladder cancer, but the association disappeared in multivariate analysis.

RESUMEN

OBJECTIVE: Intradiverticular bladder tumors (IDBT) are uncommon clinical entities. We reviewed the literature for clinical presentation, diagnosis and therapeutic options to establish recommendations for diagnostic and therapeutic management. METHODS: Bibliographic research was performed using PubMed from database inception until October 15, 2022. A pooled analysis was performed of 498 patients with IDBT presented in the literature. The evaluation included patient sex, age, diagnostic methods, symptoms, localization of the tumor, tumor staging, tumor histopathology, treatment, and the presence of recurrence. To express results, descriptive statistics were used appropriately. RESULTS: The mean age at diagnosis was 64.81 years (range 49 days to 84 years). The ratio between men and women was ≈ 24:1, suggesting a male predominance (85% male, 3.6% female). The most common presenting symptom was gross hematuria (60.88%). Most of the patients had cystoscopy (56.85%) and intravenous or computed tomography urography (52.01%). Regarding tumor staging, most of the patients were diagnosed with pT1 tumors. For the histopathology of IDBT, 87.95% of the specimens were transitional cell carcinomas and in 10.84% there were concomitant CIS. Regarding the treatment, radical cystectomy was chosen in 34.34%, partial cystectomy in 26.66%, diverticulectomy in 15.95% and transurethral resection of bladder tumour (TURBT) in 16.36% of the patients. CONCLUSIONS: Most common diagnostic tool for IDBT seems to be cystoscopy followed by computerized tomography urogram. Due to the absence of muscle layer in the diverticulum and the highgrade histology of most of them at diagnosis, cystectomy is the first therapeutic choice. However, for patients that are not considered appropriate candidates or for those presenting with lowgrade and low volume tumors, TURBT is a good option.

RESUMEN

OBJECTIVE: The aim of this study is to determine if patients undergoing radical retropubic prostatectomy with localized prostate cancer under combined (epidural-spinal) anaesthesia have any benefit over patients undergoing the procedure under general anaesthesia. MATERIAL AND METHODS: Patients with clinically localised prostate cancer, scheduled for radical retropubic prostatectomy, were allocated to undergo the operation under either general anaesthesia (GA) or under combined (epidural-spinal) (CESA) anaesthesia. Several parameters were recorded both preoperatively (medical history, biometric data, PSA, biopsy Gleason score) and postoperatively (blood pressure, heart rate, haemoglobin levels, operation time and total hospital stay). In addition, mean arterial pressure, change in heart rate, total blood loss, blood transfusions, SAS score, intravenous fluid administration and operation time were also noted down intraoperatively. Patient pain levels and total satisfaction were evaluated using appropriate questionnaires. At the 12-month follow-up, biochemical recurrence using PSA levels and urinary continence status were evaluated. RESULTS: A total of 60 patients were included (30 in each group). Intraoperatively, mean MAP and heart rate change was higher in the GA group (MAP+7,46, HR+27) and mean SAS was higher in the CESA group (+0.93). The time needed for patients' recovery was faster (-3.5 min) and hospitalization was shorter for patients in the CESA group (-0.6 days). Intraoperative blood loss, time for induction and duration of operation were not significantly different. Mean postoperative drop of haemoglobin was greater in the GA group (+0.56) while blood transfusions, VAS pain scores and amount of intravenous fluids did not differ significantly between the two groups. No complications were reported. Patient satisfaction and urinary continence were comparable between the groups and there were no cases of biochemical recurrence. CONCLUSIONS: Radical retropubic prostatectomy can safely be performed under combined (spinal epidural anaesthesia, with possible benefits of lower blood loss, less post-operative complications and earlier discharge. Both procedures have equal oncological and functional outcomes at the 12-month follow-up.

RESUMEN

OBJECTIVE: To assess the role of Cytoreductive Nephrectomy for synchronous metastatic Renal Cell Carcinoma patients in the Systemic Therapy era and beyond regarding the Overall Survival, the optimal sequence between Systemic Therapy and Cytoreductive Nephrectomy and prognostic factors. METHODS: The systematic review was conducted in accordance with the PRISMA guidelines. Bibliographic search was performed in Medline (PubMed), ClinicalTrials.gov, and Cochrane Library-Cochrane Central Register of Controlled Trials (CENTRAL). Studies included were those indexed from 2005 in an attempt to limit those conducted in the cytokine era. Risk of bias assessment was performed by two authors (K.S and T.L) using the Cochrane Collaborative Risk of Bias tool for randomized trials, the Cochrane Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool for nonrandomized studies. RESULTS: Cytoreductive nephrectomy was associated with improved overall survival in all but one of the observational studies. While in all of these studies the unvariable analysis showed improved overall survival in favor of the cytoreductive nephrectomy group in some studies the subgroup analysis showed no benefit. Regarding the optimal sequence, deferred cytoreductive nephrectomy demonstrated better results in more studies than upfront cytoreductive nephrectomy but a advantage was not clearly certain. In the analysis of possible prognostic factors for overall survival with cytoreductive nephrectomy, most common prognostic factors found were age (in 8 studies), tumor histology (in 7 studies), number of metastasis (in 6 studies), and T stage. CONCLUSIONS: Cytoreductive nephrectomy can still play an important role in wisely selected patients, although the role of cytoreductive nephrectomy in the new immunotherapy era needs to be defined.

RESUMEN

Introduction The purpose of this study was to evaluate the 24-month outcomes of ureteroureterostomy combined with unilateral nephrostomy following radical cystectomy in patients with muscle-invasive bladder cancer (BC). Materials and methods This single-center study with prospectively collected data with retrospective data analysis was carried out between December 2018 and November 2021 and enrolled 36 patients, who underwent radical cystectomy combined with ureteroureterostomy and unilateral nephrostomy. Regular renal function assessment was carried out using serum creatinine and estimated glomerular filtration rate (eGFR), and postoperative complications, endoscopic, ultrasound, and other radiological study findings were evaluated. The follow-up of the patients was carried out over a period of 24 months. Results After completion of the 24-month follow-up, the renal function proved to be slightly improved (mean serum creatinine and eGFR values of 1.38±0.72 mg/dL and 55.9±21.87 mL/min) compared to the first-year results (1.41±0.54 mg/dL and 52.10±19.64 mL/min). However, this improvement is statistically not significant (p=0.44, p=0.30). The 24-month follow-up imaging findings remained stable in 97.22% of patients compared to the first-year results, with preservation of bilateral ureteric dilatation and grade 1 dilatation of the non-drained kidney. No case of acute pyelonephritis was recorded after the completion of the second year of follow-up, in comparison to the eight patients (22.22%) of the 12-month follow-up, who suffered acute pyelonephritis. After completing of the 24-month follow-up, one patient was excluded from further analysis, due to the placement of a second permanent percutaneous nephrostomy in the non-drained kidney, due to ureteroureterostomy stenosis with consecutive hydronephrosis in the contralateral kidney and acute renal failure. No case of anastomotic leak was observed. Conclusions The function of the ureteroureterostomy combined with unilateral nephrostomy is proven to be a safe method of urinary diversion (UD) at 24 months, with minimal and easily manageable complications. Only one case of stenosis of the ureteroureterostomy with consecutive acute renal failure due to hydronephrosis in the non-drained kidney was observed. The renal function remained stable.

RESUMEN

Standard systemic therapy of advanced renal cell carcinoma (RCC) involves targeting angiogenesis, mainly through tyrosine kinase inhibitors (TKI) against the vascular endothelial growth factor receptor (VEGFR) pathway and targeting the immune checkpoints, namely, programmed death-1 (PD-1) or its ligand (PD-L1), and cytotoxic T-lymphocyte-associated protein 4 (CTLA4). With current strategies of combining these two approaches in the front-line setting, less is known about optimal selection of therapy upon development of resistance in the second and later lines of treatment for progressive disease. This review discusses currently available therapeutic options in patients who have progressive RCC after prior treatment with double immune check-point inhibitors (ICIs) or ICI-TKI combinations.

RESUMEN

PURPOSE: A prospective case-control study was conducted to evaluate glycogen deposition within the detrusor and its correlation with the urodynamic findings in patients with bladder outlet obstruction (BOO) due to benign prostate hyperplasia (BPH). MATERIAL AND METHODS: Data from 50 patients with BPH (Study Group) and 20 controls (Control Group) were analyzed. BOO was confirmed by pressure-flow studies. The main outcome was glycogen deposition within the bladder wall. Bladder tissue biopsies were obtained from all patients, and histological assessment of the detrusor glycogen content was performed using Periodate Acid Schiff's (PAS) stain. The obtained glycogen score ranged from 0 (no staining of glycogen granules) to 3 (staining of glycogen granules within the detrusor adjacent to the urothelium). RESULTS: Fifty patients and 20 controls were included. Increased glycogen deposition was observed in 37 (74%) and 2 (10%) patients in the Study and Control Group, respectively (p < 0.01, OR 25.6, 95% CI 5.2-125.8). In the subgroup analysis, no statistically significant difference was found between glycogen deposition score and IPSS, maximum detrusor pressure at maximum flow (PdetQmax) and duration of LUTS. In multivariate logistic regression, history of retention was the only variable which could predict high glycogen deposition (p = 0.019). CONCLUSIONS: Our results demonstrate increased detrusor glycogen deposition in patients with BOO due to BPH, but the amount of deposition did not seem to correlate with symptom severity and duration or urodynamic findings.

RESUMEN

Introduction Uretero-ureterostomy combined with unilateral nephrostomy is a rarely performed urinary diversion following radical cystectomy for muscle-invasive bladder cancer. The aim of this study is to assess the efficacy and safety of the procedure. Materials and methods Patients with muscle-invasive bladder cancer and poor performance status were enrolled in this retrospective, observational, single-centre study, carried out between December 2018 and November 2020. The patient's renal function was regularly assessed with serum creatinine and estimated glomerular filtration rate (eGFR). Evaluation of peri- and postoperative complications was performed based on clinical, laboratory, endoscopic, ultrasound and other radiological studies findings. The patient's status was assessed for 12 months. Results Thirty-six patients with a mean age of 77.4±8.6 years were enrolled in the study. 86.11% of patients had an American Society of Anesthesiologists Score ≥3 and 91.66% had an age-adjusted Charlson comorbidity index of ≥6. Slight deterioration of renal function, although not statistically significant, was observed. 36.11% of the patients developed permanent unilateral pelvic dilatation. Acute pyelonephritis, urosepsis, pyonephrosis and anastomotic leak were observed in 22.22%, 8.33%, 5.55% and 5.55% of patients, respectively; all were treated either conservatively and/or with minimally invasive procedures (nephrostomy, JJ-stent insertion) without any need for open surgical revision. Conclusions Ureteroureterostomy combined with unilateral nephrostomy is a safe and effective method of urinary diversion following radical cystectomy for muscle-invasive bladder cancer with easily manageable complications.

RESUMEN

Foreign objects inserted through the urethra, for sexual gratification and ending up in the urinary bladder, are rarely encountered. Patients usually present at emergency departments, reporting abdominal pain, recurrent urinary tract infections (UTIs), or haematuria. Only a few cases present without any symptoms and are incidental findings, commonly during diagnostic work-up for bladder lithiasis or recurrent UTIs. We report a case of an encrusted intermittent catheter, discovered in the bladder of a 72-year-old female patient, with a history of multiple sclerosis (MS) and recurrent UTIs. The foreign body was removed following laser defragmentation of the calculus. No indication of stone recurrence was documented during the six-month follow-up.
