RESUMEN

Introduction: Although uterine perforation is a rare but serious complication, intrauterine devices are globally popular and effective contraceptive methods. Case presentation: A 76-year-old female patient manifesting symptoms of vaginal leakage and lower abdominal discomfort was admitted to our hospital. Diagnostic imaging identified a vesicovaginal fistula and bladder calculi attributable to perforation of the bladder by an intrauterine device that had been inserted over four decades ago. The patient underwent open surgery for cystolith removal and vesicovaginal fistula repair. Conclusions: If a patient with an intrauterine device complains of bladder stones or ongoing lower urinary tract symptoms, bladder perforation caused by the device should be considered in the differential diagnosis.

RESUMEN

Bladder calculi commonly develop in patients with poor bladder emptying or those with retained foreign bodies within the bladder, leading to irritative voiding symptoms, hematuria, and an increased likelihood of refractory urinary tract infections. While many techniques exist for the treatment of bladder calculi, including endoscopic and open-surgical approaches, our novel technique may help manage exceptionally large or difficult-to-treat bladder calculi effectively. We present three patients with symptomatic bladder calculi ranging from 1.3 cm to 6.8 cm in size who were successfully treated by using our novel technique. Percutaneous access to the bladder was obtained by using a suprapubic catheter trocar and sheath to enable the utilization of a dual-action lithotriptor. Sheath insertion and lithotripsy were performed under direct visualization with a rigid cystoscope via the native urethra. This technique is easily learned and can be safely employed in patients in whom other methods may pose risks of higher morbidity.

RESUMEN

INTRODUCTION AND IMPORTANCE: Bladder stones, although rare in a healthy bladder, can emerge due to various factors, including obstructions in urinary flow, recurrent infections, and foreign bodies. Intrauterine contraceptive devices (IUCDs) are known for their potential to migrate from the uterine cavity, leading to unusual complications such as bladder stone formation. CASE PRESENTATION: A 52-year-old woman, previously treated for a complicated urinary tract infection, presented with intermittent lower abdominal pain, dysuria, and hematuria. She had a history of an IUCD insertion 15 years earlier, which was later documented as missing. Diagnostic imaging revealed a large bladder stone, encasing the previously inserted IUCD. An open vesicolithotomy was performed, during which a stone measuring 6 × 5 cm was removed, revealing the IUCD within. The patient had an uncomplicated recovery with no further urinary tract infections at a 6-month follow-up. CLINICAL DISCUSSION: The migration of an IUCD can lead to various complications, depending on its final location. The formation of bladder stones around a migrated IUCD is a rare but significant complication, necessitating a thorough diagnostic approach. Radiography and ultrasonography proved sufficient for diagnosing the intravesical migration in this case. CONCLUSION: This case underscores the importance of considering a migrated IUCD in the differential diagnosis of patients presenting with urinary symptoms, especially those with a history of a missing IUCD. Timely diagnosis and management are crucial in preventing further complications.

RESUMEN

BACKGROUND: Evidence-based guidelines are published by urological organisations for various conditions, including urolithiasis. In this paper, we provide guidance on the management of kidney stone disease (KSD) and compare the American Urological Association (AUA) and European Association of Urologists (EAU) guidelines. METHODS: We evaluate and appraise the evidence and grade of recommendation provided by the AUA and EAU guidelines on urolithiasis (both surgical and medical management). RESULTS: Both the AUA and EAU guidelines provide guidance on the type of imaging, treatment options, and medical therapies and advice on specific patient groups, such as in paediatrics and pregnancy. While the guidelines are generally aligned and based on evidence, some subtle differences exist in the recommendations, but both are generally unanimous for the majority of the principles of management. CONCLUSIONS: We recommend that the guidelines should undergo regular updates based on recently published material, and while these guidelines provide a framework, treatment plans should still be personalised, respecting patient preferences, surgical expertise, and various other individual factors, to offer the best outcome for kidney stone patients.

RESUMEN

PURPOSE: To compare the postoperative outcomes of male patients who underwent bladder stone (BS) removal, with or without concomitant benign prostatic hyperplasia (BPH) surgery. PATIENTS AND METHODS: All men aged > 50 years who underwent BS removal at two French university hospitals between 2009 and 2018 were retrospectively reviewed. Four binary outcome criteria were identified during the follow-up: early postoperative complications, stone recurrence, subsequent surgery for BS or BPH, and late surgical complications. A composite score ranging from 0 to 4 was calculated by combining the four criteria. RESULTS: A median follow-up period of 42 months was observed in 179 patients. Of these, 107 patients were in the "concomitant surgical treatment" (CST) group and 72 in the bladder "stone removal alone" (SRA) group. The CST group presented higher baseline post-void residual volume (105 vs. 30 ml, p = 0.005). Patients who underwent CST had a significantly lower rate of BS recurrence (12% vs. 39%; p = 0,001) and underwent fewer subsequent surgeries (14% vs. 44%; p < 0.001). There was no significant difference in the early (51% vs. 35%, p = 0,168) and late (26% vs. 17%, p = 0,229) complications rates between the two groups. A better composite score was observed in the CST than in the SRA, but the difference was not significant (3.07 vs. 2.72, p = 0.078). CONCLUSION: As CST increases morbidity and decreases the risk of reoperation, each situation should be considered, taking into account patient choice and comorbidities.

RESUMEN

A 34-year-old man was admitted to the hospital presenting repeatedly urinary urgency for 3 years and yellow-green lithotripsy foreign body in urine for 1 month. Initially, he was diagnosed with a giant bladder calculi. After a cystoscopy exam and a lithotripsy for bladder calculi, Appendiceal vesical fistula was finally diagnosed and treated with a laparoscopic surgery. We report a rare case of appendiceal vesical fistula，first presenting as giant bladder calculi，and successfully treated with minimal invasive surgery We report this case and reviewed literature to improve the understanding of this disease and reduce misdiagnosis and missed diagnosis.

RESUMEN

Introduction and Objective: A variety of laser sources are available to treat bladder stones. The aim of this study was to compare time and cost efficiency of the thulium fiber laser (TFL) to four holmium lasers (HLs) with different powers or technologies, including MOSES™ during simulated cystolithotripsy. Materials and Methods: In a benchtop simulation of laser cystolithotripsy, 25 identical 4-cm BegoStones (calcium oxalate monohydrate consistency) were placed on a grid within a 3D-printed bladder model. Lasers were operated at maximal energy, using a 550 µm fiber. Lasers compared were as follows: 60 W TFL, 120 W HL with MOSES, and conventional 120, 100, and 30 W HLs. Five trials were performed for each laser with endpoints of laser time, total time, number of fiber strippings, and total energy. Cost-effectiveness was modeled using laser purchase price, fiber, and operating room (OR) time cost. ANOVA with Tukey's B post hoc was performed to compare outcomes. Spearman's test was used to assess correlation between laser power and procedure time. Results: The laser and total operating times were significantly different between the five systems (p < 0.001). The 120 W HL with MOSES was the fastest with 60.9 minutes of laser and 68.3 minutes of procedure times, while the 30 W HL was the slowest with 281.2 minutes of laser and 297.5 minutes of procedure times. The 60 W TFL was faster than the 30 W HL, but slower than the higher power HLs. Higher laser power was associated with shorter procedure time (Rs = -0.98; p = 0.002). When estimating cost per procedure, the MOSES HL was the cheapest, but had the highest purchase cost. The TFL was not cost-effective for large bladder stones compared with the 100 W HL. Conclusions: When treating large bladder stones, total laser power was highly correlated with laser and procedure times and the TFL was limited by its total power. The most cost-effective laser for use will depend on the case volume.

RESUMEN

INTRODUCTION AND IMPORTANCE: Bladder calculi after radical prostatectomy is rare and usually associated with migrated clips into the bladder forming a nidus. We present a patient with multiple bladder calculi resulting from bladder neck stenosis after radical prostatectomy causing bothersome lower urinary tract symptoms. He had an associated hypertrophic scar. CASE PRESENTATION: A 60-year-old man of African ancestry presented with recent onset of irritative urinary symptoms three years after radical prostatectomy. Abdomen pelvic ultrasound and pelvic X-ray revealed a urinary bladder calculus. Examination of the previous radical prostatectomy scar found him to have a hypertrophic scar. He had urethroscopy with bladder neck incision for bladder neck stenosis and cystolithotomy with resolution of the symptoms. CLINICAL DISCUSSION: The presentation was that of dysuria and frequency three years after radical prostatectomy. The cause of the symptoms was diagnosed after an abdomen pelvic ultrasound and pelvic X-ray as multiple bladder calculi. This is a rare finding with the few reported cases associated with clips that migrated to the urinary bladder forming a nidus for the calculi. This was of consideration in the case presented, however, the findings at urethroscopy revealed bladder neck stenosis suggesting stasis as possible cause of the bladder calculi. The symptoms resolved after bladder neck incision and cystolithotomy. CONCLUSION: In addition to clips forming a nidus for calculi in the urinary bladder after radical prostatectomy, bladder neck stenosis being the cause of urinary bladder calculi should be considered in a patient with hypertrophic scar.

RESUMEN

Giant bladder calculi are rare and long-term usage of cystostomy could cause stone formation. Due to the lack of evidence on giant bladder calculi and the long-term usage of cystostomy can cause bladder calculi formation, we provide a case study of a man with a neglected cystostomy with giant bladder calculi for 4 years. A fixed mass was discovered in the suprapubic region. Ultrasound examination revealed 4.1 × 5.5 cm bladder calculi and contracted left kidney. Bipolar voiding cystourethrography portrayed stricture in pars pendular and membranacea, uneven bladder wall, and 4.5 × 4.5 cm bladder calculi. The stone was extracted, and the bladder filling test revealed a small bladder capacity. Since the patient refused urethral reconstruction and bladder augmentation, he was discharged with another cystostomy catheter. Six-month follow-up revealed no forming stones. Neglected cystostomy catheter can cause giant bladder calculi. Prompt diagnosis and treatment should be made to manage this condition to reduce the likelihood of bladder cancer.

RESUMEN

Bladder calculi are rare in women. We report a case of bladder calculi complicating irreducible uterovaginal prolapse. It provides diagnostic and operative challenges to the management team. A 77-year-old woman presented with irreducible complete uterovaginal prolapse. Bladder stones were appreciated on examination and confirmed with imaging. The patient was managed surgically with transabdominal hysterectomy with bilateral uterosacral colpopexy followed by cystolithotomy. The patient's postoperative course was uncomplicated, and she had an uneventful recovery at her 3-month postoperative visit without a recurrence of prolapse and gained good continence. The presence of bladder calculi should be considered in the setting of irreducible pelvic organ prolapse. The abdominal approach of cystolithotomy with a concomitant hysterectomy and vaginal apical suspension is safe and effective.

RESUMEN

BACKGROUND: Giant stones of the urinary bladder (GSBs) are rare and usually presented as case reports. We aimed to assess the clinical and surgical characteristics of GSBs and identify their predictors. METHODS: A retrospective study of 74 patients with GSBs who presented between July, 2005 and June, 2020 was performed. Patients' demographics, clinical presentations, and surgical peculiarities were studied. RESULTS: Older age and male gender were risk factors for the occurrence of GSBs. The irritative lower urinary tract symptoms (iLUTS) were the main presenting symptoms (97.3%). Most patients were treated with cystolithotomy (90.1%). Univariate analyses showed that solitary (p < 0.001) and rough surface (P = 0.009) stones were significant factors for occurrence of iLUTS as the presenting symptoms. Also, the severity of symptoms (p = 0.021), rough surface (p = 0.010) and size (p < 0.001) of stones, and farmer occupation (p = 0.009) were significantly associated with adherence of the stone to the bladder mucosa at surgery. In multivariate analysis, the rough surface (p = 0.014) and solitary (p = 0.006) stones, and concomitant ureteral stones (p = 0.020) were independently associated with iLUTS as the main presentation. However, the stone size and severity of iLUTS were the independently associated factors for adherence of GSBs to the bladder mucosa. CONCLUSIONS: Solitary GSB, rough surface and the association with ureteral stones are independent risk factors for the occurrence of long-standing iLUTS. The stone size and severity of iLUTS were the independent predictors of adherence of GSBs to the bladder mucosa. Cystolithotomy is the main treatment, but it may be more difficult when there is bladder mucosa adherence.

RESUMEN

BACKGROUND: The formation of bladder calculi is a complex multifactorial process. Our objective was to identify predictors of bladder calculi in men. METHODS: This cross-sectional study was conducted at a regional public hospital. We used medical records from 2017 to 2019 for men diagnosed with urinary calculi or benign prostatic hyperplasia (BPH). The diagnosis of urinary calculi was based on urinalysis, plain x-ray, and ultrasonography (USG). The diagnosis of BPH was based on digital rectal examination (DRE), USG, and American Urological Association (AUA) Symptom Index to assess the severity of BPH. The data were analyzed using Kruskal-Wallis, Mann-Whitney U, Chi-square tests, and binary logistic regression. RESULTS: Of 2010 study participants, 66.0% were men with urinary calculi, 39.7% had BPH, 21.0% were aged 70 years or more, 12.5% lived in limestone mountain areas, and 24.6% had occupations that were mainly outdoors. Urinary calculi in men with BPH were found in the urethra (3.0%), bladder (27.6%), ureter (2.2%), and kidney (1.1%). Of all men with urinary calculi, the odds of having bladder calculi in men aged 70 years or more was 13.484, 95% confidence interval (95% CI): 8.336-21.811; In men with BPH was 11.182, 95% CI: 6.440-19.416; In men who lived in limestone mountain area was 1.894, 95% CI: 1.242-2.887; In men whose occupation is mainly outdoor was 3.240, 95% CI: 1.954-5.375, compared to reference groups. CONCLUSIONS: Age, BPH, geography of residence, and occupation were predictors of bladder calculi in men.

RESUMEN

Introduction: This single-center experience describes the indications, novel technique, and outcomes of performing 14F super-mini percutaneous cystolitholapaxy (14F-SMPCCL). Materials and Methods: Cases between 2019 and 2022 were retrospectively identified with surgical outcomes recorded. Using percutaneous access to the bladder, an endoscope was inserted through the ClearPetra 14F super-mini sheath and laser lithotripsy completed with stone fragments suctioned out. Results: Sixteen cases were included in the study and all patients were adults. Average conglomerate stone size was 28.1 mm (range = 10-50 mm). Average operative time was 60.0 minutes (range = 23-110 minutes). Visual stone-free rate was 91.7%, radiologic stone-free rate was 81.3%, and average postoperative length of stay was 1 day. One patient developed urosepsis postoperatively and there were no other complications. Conclusion: The novel technique of 14F-SMPCCL is safe and feasible for treating large burdens of bladder stones with a conglomerate size of ∼2.5 to 5 cm. Active suction allows for efficient removal of stone fragments.

RESUMEN

Inguinoscrotal herniation of the bladder is an uncommon condition. Clinicians should have a high index of suspicion for involvement of the bladder within a hernia when the lower urinary tract urinary symptoms are concurrently present in patients presenting with a painful groin lump. We report the case of a patient who presented with an inguinoscrotal hernia involving the urinary bladder, which was irreducible due to the fact that the herniated portion of the bladder contains multiple containing calculi. The patient underwent successful operative repair of the hernia and had an uncomplicated post-operative course. Key takeaway messages for clinicians are that the presence of lower urinary tract symptoms in a patient concurrently presenting with a groin lump should raise suspicion of bladder involvement within the hernia and that pre-operative imaging is valuable to identify the contents of the hernia to allow safe operative planning and to reduce the risk of bladder injury during surgery.

RESUMEN

Double-J ureteral stents are an invaluable tool in urology and are one of the most widely used stents in the world. However, when left in situ for prolonged periods, so-called "retained" ureteral stents can lead to numerous complications such as migration, hematuria, encrustation, or stent occlusion. These complications present severe challenges in urologic management. Notably, encrustation of ureteral stents may increase the risk of renal impairment and other potentially life-threatening complications. Here, we present the case of a 34-year-old female with a left double-J ureteral stent who presented to the Emergency Department (ED) with a one-day history of left flank pain and febrile urinary tract infection.

RESUMEN

Intrauterine device (IUD) is the second most widely used method of contraception worldwide. Up to 14% women prefer IUD for its attractive advantages such as cost effectiveness, high efficiency, and low complication rate. Despite these advantages, however, some complications may occur. One of these complications is uterine perforation and migration of the device to involve adjacent viscera such as peritoneum, bowel, vessels, and rarely bladder. IUD migration into the urinary bladder is uncommon, and only 70 cases are reported in the literature. Recurrent urinary tract infection and bladder calculi are the commonest presentations, and, rarely, women can present with gross hematuria. A high index of suspicion is needed in the evaluation of women who report pregnancy after IUD insertion as it might be the first clue to suspect migration. A forgotten and long-standing IUD increases the risk of uterine perforation and migration. A routine abdominal radiography, cystoscopy, and transvaginal ultrasonography are diagnostic. A computed tomography can also be employed in selected cases to delineate anatomic relations. Urologists should consider a vesical foreign body such as migrated IUD in women with recurrent lower urinary infections. Gross hematuria in a young woman should alert the urologist, and the evaluation should address a detailed contraceptive history. Every migrated IUD should be removed via endoscopy, laparoscopy, or open surgery. Proper follow-up and education of women before and after IUD insertion is also recommended to pick up on complications in time. Here, we report the successful open surgical treatment of a woman who had a forgotten IUD for 15 years and ultimately presented with gross hematuria due to trans-vesical migration. As to our literature search, there was no similar case reported from a urology center from Ethiopia.

RESUMEN

INTRODUCTION AND IMPORTANCE: Giant bladder stone is a rare entity in the modern urological practice. There have been limited reports on giant bladder stone with concomitant renal failure and bladder cancer available in the literature. CASE PRESENTATION: A 43-year-old male patient presented to the ER with chronic gross hematuria, dysuria, intermittent urination, and bilateral flank pain. Laboratory investigations showed markedly elevated blood urea and serum creatinine levels at admission. Urinalysis revealed pyuria and hematuria with positive nitrite. The kidney-ureter-bladder (KUB) film showed a large single urinary bladder stone measuring 10 × 9 cm. Ultrasound examination revealed bilateral hydronephrosis. Suprapubic cystolithotomy was performed, and the stone was extracted from the bladder. A suspicious bladder mass was found incidentally. Biopsy of the mass showed a low-grade urothelial carcinoma with glandular differentiation and invasion of lamina propria, staged pT1NxMx. The kidney function test marked unimprovement of serum urea and creatinine after the surgery. CLINICAL DISCUSSION: Open cystolithotomy was performed to release the obstruction and preserve renal function. Chronic obstruction, long-standing chronic inflammation, and urinary tract infection might play a vital role in the progression of kidney injury and the development of bladder cancer. CONCLUSION: Complications that follow giant bladder stone could be long-lasting and taxing for the sufferer. The risk of renal failure and bladder cancer precipitated by chronic obstruction and mucosal injury should be considered when encountering such case.

RESUMEN

Chronic irritation of bladder by urinary bladder calculus is a known risk factor for bladder cancer. The use of Wrigley's obstetrical forceps in general surgical practice is a rare event. Herein, we report a case of a giant urinary bladder calculus which was removed by Wrigley's obstetrical forceps during open cystolithotomy. The bladder biopsy showed squamous cell carcinoma of the bladder. With this report, we aim to create an awareness among surgeons about the role of the Wrigley's obstetrical forceps during open cystolithotomy, and the role of taking urinary bladder biopsy from chronically inflamed/unhealthy sites.
