Robotic-assisted intravesical mesh excision following retropubic midurethral sling.

INTRODUCTION AND HYPOTHESIS: Intravesical mesh is an uncommon complication following synthetic midurethral sling placement. Management options have included endoscopic techniques such as laser ablation or surgical excision. We present our technique for robotic-assisted excision of intravesical mesh following a retropubic midurethral sling. METHODS: The patient is a 66-year-old woman with a remote history of laser ablation of intraurethral mesh after midurethral sling, and persistent symptomatic intravesical mesh with associated stone at the bladder neck and right bladder wall. Robotic excision of the intravesical mesh and stone was performed by entering the space of Retzius, carrying the dissection along the right arm of the retropubic sling, performing two cystotomies to free and remove the mesh, and finally closing the cystotomies in two layers. RESULTS: The patient was discharged on postoperative day 1. A cystogram prior to catheter removal showed no extravasation and a competent bladder neck. She reported no new stress incontinence and had improvement in overactive bladder symptoms. CONCLUSIONS: Robotic excision of intravesical mesh after synthetic midurethral sling was safely performed in this patient who had multiple areas of intravesical mesh. Management aspects reported here may be helpful for complex presentations of intravesical mesh.

Bladder Stone Formation due to Intravesical Migration of the Intrauterine Device: A Report of 2 Cases.

INTRODUCTION: Approximately 5% of bladder stones occur in women and are usually associated with foreign bodies or urinary stasis. Spontaneous migration of the intrauterine device (IUD) into the bladder is a rare complication. In this report, we present 2 cases of migrated IUD who had undergone surgery at our clinic due to bladder stones. CASE PRESENTATIONS: We detected migrated IUDs into the bladder in 2 female patients, aged 37 and 56 years, who presented with lower urinary tract symptoms and urinary tract infection. In the first case, endoscopic cystolithotripsy was performed, and the IUD was removed without complications. In the second case, the IUD could not be removed endoscopically since it had fractionally invaded the bladder wall, and the IUD was removed without complications by performing an open cystolithotomy. CONCLUSION: A comprehensive gynecological history should be taken from every female patient presenting with recurrent urinary tract infections and lower urinary tract symptoms. If these patients have a history of IUD placement, the possibility of the intravesical migration of this device should be kept in mind.

Intrauterine device migration into the bladder leading to stones formation.

An intrauterine device (IUD) is a popular method of contraception mainly used in developing countries. Perforation is one of the most serious but a rare complication secondary to the insertion of an IUD, while perforation into the intravesical organs such as the bladder is even more rare. A 30-year-old multipara in early 30s, with two previous caesarean sections (CS) and one curettage, was found to have her IUD puncturing the bladder during a cystoscopy procedure to remove her bladder stones. Transvesical migration of an IUD is an uncommon complication with a high rate of calculi formation, which is thought to be caused by the IUD's lithogenic potential. Imaging approaches such as ultrasound and pelvic X-rays are considered imperative in the accurate diagnosis. Any migrated IUD should be removed regardless of location. Prompt and continual monitoring of women using an IUD is essential and in a case where the IUD has migrated, the removal using the endoscopic approach is a safe and effective method.

Age, Benign Prostatic Hyperplasia, Geography of Residence, and Occupation are Predictors of Bladder Calculi in Men: A Three-Year Data Analysis

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 (AU)

Bladder stone caused by misplaced intrauterine contraceptive device: a case report.

Intrauterine Contraceptive Device (IUCD) when placed in the uterine cavity is used for contraception or treatment of intrauterine adhesion, but it has become a cause of unintended bladder stone due to wrongful placement or migration. It may cause blood in urine and painful urination. Pelvic ultrasound and X-ray were used to make the diagnosis of the bladder stone with the embedded IUCD, which was removed by open vesicolithotomy through a Pfannenstiel suprapubic incision. Cases such as this are highly preventable if post procedure and routine annual pelvic ultrasonography are emphasized as standard practice following IUCD insertions.

IUCD as bladder stone.

Intrauterine Contraceptive Devices (IUCDs) are commonly used in low to middle-income countries. IUCD migration into the adjacent organs, especially bladder, is exceptionally rare, though important to exclude. A 55-year-old para three post-menopausal female with history of recurrent urinary tract infections presented with lower urinary tract symptoms. Urine examination was indicative of Eschericia coli infection. Pelvic radiograph revealed an intravesical calculus having a T-shaped extension. Cystoscopy confirmed a bladder stone encasing an encrusted IUCD. Cystolithotripsy was performed, fragmenting the calculus which was then removed along with the IUCD in toto. IUCDs require regular evaluation to confirm their correct position. Gynecologists must properly counsel the patient so that the incidence of forgotten IUCDs can be minimized. Urologists need to be aware of these cases so that gynecological history is kept in mind while evaluating females with urinary symptoms. Serious complications such as intravesical migration are extremely rare but possible.

Delayed ileal neobladder fistula caused by bladder stones: a case report.

BACKGROUND: Ileal neobladder fistula is a rare complication after radical cystectomy, with an incidence of approximately 0.7%. At present, there are scattered reports of vesicoileal fistula, but there are no reports of ileal neobladder fistula (INF) caused by bladder stones. In this paper, a case of ileal neobladder fistula caused by chronic stimulation of bladder stones was successfully diagnosed and treated. CASE PRESENTATION: A 68-year-old man who had undergone radical cystectomy and an orthotopic ileal neobladder procedure 10 years prior presented with refractory diarrhoea and oliguria and was diagnosed with ileal neobladder fistula caused by chronic stimulation of bladder stones. We performed fistulectomy, cystotomy, partial ileectomy, and end-to-end ileal anastomosis, and the patient recovered and was discharged after the operation. CONCLUSION: Urinary calculi are delayed complications of orthotopic neobladder construction after total cystectomy. Bladder stones are a rare complication of ileal neovesical fistula, which can cause neovesical cutaneous fistula. It is difficult to diagnose through routine examination and easily misdiagnosed as acute gastroenteritis. Surgery is an effective treatment for INF and can achieve a good prognosis.

Neglected double-J stent with giant bladder stone: a case report.

Double-J (DJ) stents have been widely utilized in urological practice. They are commonly used to relieve ureteral obstruction. Serious complications may occur when stents are left in place for long periods of time. In the present paper, we report a patient with a neglected DJ stent that had been inserted for five years after uterus-tumor surgery and led to a bladder stone. We report a case of a female who presented a bladder stone with a right DJ stent in the pelvic cavity. The stone was evident in radiological examination in an incidental finding. The treatment was transurethral cystolithotripsy. This case reminds us of the necessity of providing enough information and appropriate knowledge pertaining to the insertion of a ureteral stent. Transurethral cystolithotripsy is one of the treatment methods and can be suggested as a definitive method in consideration that it is a clinically effective and safe intervention.

Tubeless percutaneous nephrolithotomy (PCNL) for forgotten and retained stent in renal allograft recipient: an interesting case report and lessons learnt.

Complications after renal allograft transplantation are not so uncommon. Most complications are related to graft rejection, immune-suppressive drug toxicity and the operative procedure. Stents are placed after a transplant to prevent urine leak at the site of ureteric reimplantation, to facilitate an early healing in immune-suppressed individuals and to prevent obstruction at the site of ureteral anastomosis. We report a case of a renal allograft recipient with a forgotten ureteral double J stent. where the stent remained in situ for more than 4 years and further complicated by encrustation and stone formation at both the bladder and renal pelvic ends. The stone over the bladder coil was removed by holmium laser cystolithotripsy while the encrusted renal pelvic coil was removed by percutaneous approach. This case is presented for its rarity and also to emphasise on the need for maintenance of a stent register in order to ensure avoidance of such preventable complications.

[A CASE REPORT OF VESICAL CALCULUS FORMATION WITH CHROMIC CATGUT AT THE URETEROVESICAL ANASTOMOTIC SITE 28 YEARS AFTER RENAL TRANSPLANTATION].

A 69-year-old man underwent renal transplantation due to chronic renal failure of unknown cause in 1991. Furthermore, in 2012 he again underwent renal transplantation due to renal graft dysfunction with focal segmental glomerulosclerosis. After the second renal transplantation, his renal function has been stable. In 2019, he presented to the urology department with gross hematuria. Cystoscopy revealed a 2 cm vesical calculus at the dome of the bladder near the right lateral wall. Therefore, we performed transurethral lithotripsy using the holumium laser method. The vesical calculus was crushed, revealing a suture at the center, suggesting the suture as the cause. We tried to remove the suture during operation, however, it was impossible. Although the remaining suture posed a risk for calculus development, there has been no recurrence of a calculus for 6 months after the operation. This case reports a vesical calculus at the ureterovesical anastomotic site, wherein the core was an absorbable suture used during the initial renal transplantation. It should be taken into consideration that there is a possibility of anastomotic calculus occurrence with absorbable sutures, even long after renal transplantation.

Urinary bladder stone due to retained indwelling ureteral stent: A case report.

RATIONALE: The indwelling ureteral stents is a common procedure in routine urological practice. The double-J (D-J) stent is the most common type of stents used and is indicated mainly for short-term urinary drainage and prevention of obstruction and infection. However, prolonged indwelling stents may result in disastrous complications, such as hematuria, infection, encrustation, and stone formation. In this context, the persistence of stent in situ might play a key role as a nidus in deposition of urinary sediment, then forming calculus. Although the encrustation may become more serious as time goes on, large bladder stones are relatively rare. However, the serious encrustation and giant stone may complicate or exacerbate the conditions in turn. PATIENT CONCERNS: A 45-year-old female patient who underwent right ureteral stent placement after open ureterolithotomy 6 years ago complained of dysuria, urinary frequency, and urgency over 2 months. DIAGNOSIS: The kidney ureter bladder (KUB) x-ray showed the presence of a giant stone in the bladder and an entire D-J stent. The computed tomography (CT) urography scans revealed normal left kidney, right hydronephrosis, and an encrusted D-J stent with the significant stone, diameter 4.2 cm with a CT value of 1211.0 ±â€Š221.6 HU, on the vesical coil. On the basis of these auxiliary examinations, the case was diagnosed as cystolith and prolonged-indwelling stents. INTERVENTIONS: Pneumatic ballistic lithotripsy was used for crushing the bladder calculi followed by the successful extraction of intact D-J ureteral stent. OUTCOMES: No residual stone was detected on postoperative KUB x-ray and CT urography scans. Patient recovered well and was discharged 10 days after surgery. Semi-annual ultrasound examination was suggested to monitor the effect of therapy. LESSONS: This case reminds us that it is crucial to take various measures to avoid the forgotten ureteral stent and its unfortunate late complication.

Fixing tacks induced bladder erosion and recurrent stones following laparoscopic inguinal hernia repair: a case report.

BACKGROUND: Hernia mesh erosion into the urinary bladder is a rare complication of hernioplasty, and mesh immigration is the most probable pathophysiology. There is no report describing mesh erosion induced by fixing tacks in inguinal hernia repair. CASE PRESENTATION: A 37-year-old man was admitted to our hospital with frequency, urgency and odynuria for 3 months. He received open right inguinal hernia repair in September 2014, and right laparoscopic hernioplasty for recurrence of the inguinal hernia in May 2015. In February 2019, he underwent a day-case transurethral cystoscopic operation for urethral and bladder stones. Cystoscopy revealed the existence of bladder stones and part of the eroded mesh on the right anterior wall, for which an open partial cystectomy was performed. The patient was followed up for 3 months postoperatively, during which no further mesh erosion or stone recurrence was detected by cystoscopy. CONCLUSION: This is the first case report describing mesh erosion into the urinary bladder by fixing tacks following laparoscopic inguinal hernia repair. In such a case, the eroded mesh and tacks need to be removed completely, but the effectiveness of a single transurethral procedure needs to be verified in more cases.

Radiographic features of suspected suture-associated cystic calculi in dogs.

This retrospective case series describes the radiographic features of suspected suture-associated cystic calculi in six dogs with a history of at least one or multiple prior cystotomies. One of the dogs presented twice. Suspected suture-associated cystic calculi were multifocal, short, predominantly linear mineral opacities localized in the center of the urinary bladder on abdominal radiographs. One patient (n = 1) presented with multifocal round, pin point, and linear radiopaque calculi. The calculi were all calcium oxalate in composition. On gross examination, the calculi had a hollow center. Six cystotomies used monofilament absorbable suture material (polydioxanone [n = 4] or poliglecaprone 25 [n = 1]) in prior cystotomies. Suture material in two of the cases was unknown. Suspected suture-associated cystic calculi are a rare occurrence in veterinary medicine but should be considered in dogs that have a history of prior cystotomy, hollow core on gross analysis, and radiographic evidence of mineral opaque, predominantly linear, cystic calculi.

A Bladder Stone 28 Years After Burch Colposuspension.

An 86-year-old lady was referred for a 3-cm bladder stone 28 years after Burch colposuspension. Cystoscopy showed a stone over a nonabsorbable suture, eroding from the right anterolateral bladder wall. The patient underwent a transurethral holmium laser lithotripsy and thulium laser removal of the eroded bladder wall. A high index of suspicion of suture erosion should always be present in case of de novo symptoms in women who underwent colposuspension, even in the long-term period.
