Bladder Perforation and Vesico-Haematoma Fistula: An Uncommon Complication of Rectus Sheath Haematoma

Introduction

Rectus sheath haematoma (RSH) has become increasingly common but is often underdiagnosed. Prompt diagnosis will avoid unnecessary investigations and procedures, resulting in early treatment and a better outcome.

Case description

We described a case of a spontaneous RSH with intraperitoneal extension and formation of a vesico-haematoma fistula, which was initially misdiagnosed as a urinary tract infection. The diagnosis was made ten days after admission, when a CT scan showed an over-16 cm RSH with intraperitoneal extension, bladder perforation and a vesico-haematoma fistula. The patient was managed conservatively.

Discussion

RSH accounts for less than 2% of acute abdomen cases and is often unrecognised. Its presentation can mimic other intra-abdominal pathologies, and the diagnosis is often delayed or missed. Complications can arise from an RSH although it is generally viewed as a self-limiting condition.

Conclusion

RSH has become increasingly common, and we would like to highlight the need to include abdominal wall pathologies in the initial differential diagnoses of acute abdomen to avoid delay in diagnosis.

LEARNING POINTS

Rectus sheath haematoma has become increasingly common due to the use of anticoagulants.The presentation can be non-specific and mimic other intra-abdominal pathologies. Misdiagnosis or delayed diagnosis can result in complications and unnecessary invasive procedures.Abdominal wall pathologies including rectus sheath haematomas should be included in initial differentials of acute abdomen.

Confirmation of intestinal and bladder perforations in a peritoneal dialysis patient using SPECT/CT: a case report and review of literature

Background

Peritoneal dialysis (PD) is a common treatment method for patients with renal failure. While peritonitis and tube floating migration are commonly observed complications, visceral perforation caused by PD is relatively rare. We present a case report of a patient undergoing PD due to renal failure, who encountered two instances of visceral perforation. In both occurrences, Single-Photon Emission Computed Tomography/Computed Tomography (SPECT/CT) played a pivotal role in providing accurate diagnoses and precise localization of the perforation sites. This report underscores the paramount significance of SPECT/CT in diagnosing visceral perforations in the context of PD.

Case presentation

A 73-year-old elderly male has been undergoing PD for 1 year due to renal failure. Recently, there has been impaired drainage of the PD catheter. The clinical team suspected the occurrence of peritonitis. The patient underwent a 99mTc Sodium Pertechnetate (99mTc-NaTcO4) SPECT/CT examination, which identified intestinal perforation. After 20 days of conservative treatment, a SPECT/CT follow-up examination revealed the resolution of the intestinal perforation, but a new bladder perforation emerged. The dialysis catheter was methodically and gradually withdrawn in stages while simultaneously performing bladder decompression. Following these interventions, the patient remained free from peritonitis and cystitis.

Conclusion

The utilization of SPECT/CT proved to be highly valuable in the accurate diagnosis of visceral perforation, a relatively rare complication observed in PD patients.

Bladder Perforation in the Elderly: Unraveling the Diagnostic Challenges With Magnetic Resonance Imaging

Bladder perforation, a significant urological emergency, presents a diagnostic challenge due to its diverse etiologies and varying clinical manifestations. This paper discusses a rare case of bladder perforation in an 87-year-old woman with a history of hypertension and previous stomach and uterine cancer. The patient was admitted with a urinary tract infection and subsequently experienced mild abdominal discomfort and reduced urinary output, prompting further investigation. Imaging studies revealed bladder wall thickening and ureterohydronephrosis, raising suspicion of a bladder tumor. Intriguingly, a catheter-related bladder perforation was identified through MRI. This case emphasizes the importance of considering bladder perforation as a potential complication, especially in elderly patients with indwelling catheters. Clinicians must maintain a high index of suspicion and employ appropriate diagnostic modalities to ensure timely recognition and suitable management of this rare condition.

Bladder perforation as a rare complication of urethra sounding with a blunt marking pen

Urethral sounding is the insertion of an object or liquid into the urethra for sexual gratification. It is associated with a substantial risk of loss of the foreign body in the bladder, urethral strictures or infection. Bladder perforation is a rare complication of urethral sounding which is usually associated with a sharp object. Here, we present the case of a young adult female presenting with abdominal pain after practicing urethral sounding with a blunt marking pen. She was found to have an intraperitoneal bladder perforation, requiring exploratory laparotomy and bladder repair.

Transient Trabecular Formation in the Bladder and Delayed Free Air due to Traumatic Intraperitoneal Bladder Rupture

An H-section steel bar that had been set against the wall fell and hit the abdomen and then both legs of a 33-year-old Chinese man. As his vital signs were stable and his chief complaint was leg pain, he was transferred to a local medical facility. After the confirmation of gross hematuria by an indwelling a bladder catheter there, he was transported to our hospital. On arrival, his vital signs were stable. His main complaint was foot pain. He had a scabbing injury at the scrotum and bilateral foot joint deformity. Whole-body computed tomography (CT) from head to toe revealed trabecular formation in the bladder and slight fluid collection in the rectovesical pouch, as well as bilateral fracture-dislocations at the ankles. The urinary tract injury and the fluid collection in the rectovesical pouch were managed conservatively, and the lower limbs were treated tentatively. Follow-up CT on day 3 revealed multiple free air pockets in the intra-abdominal cavity, which was considered to indicate perforation of the duodenal ulcer and treated conservatively. However, he showed abdominal pain on day 7, and repeated CT revealed increased fluid in the intra-abdominal cavity. Urgent laparoscopy showed intact bowels and perforation of the bladder that was closed by suturing. He ultimately obtained a survival outcome. This is the first case of transient trabecular formation in the bladder and delayed free air due to traumatic intraperitoneal bladder rupture. This unique case adds another radiological finding to the list of documented etiologies of traumatic bladder perforation.

Acute Perforated Appendicitis Complicated by Necrotizing Fasciitis and Bladder Perforation

Acute uncomplicated appendicitis is a common surgical disease that has been well-studied, and its overall mortality has decreased over time. However, delay in treatment can be associated with rare complications such as necrotizing fasciitis, which carries a high mortality rate, and bladder perforation. We present such a case in an 81-year-old female with no significant surgical history who presented to the emergency department with four days of abdominal pain. A CT scan revealed extensive subcutaneous air in the abdominal wall, an inflamed appendix, and a periappendiceal abscess. During subsequent exploratory laparotomy, she was also found to have bladder perforation. She underwent debridement of necrotic tissue of the abdominal wall, appendectomy, drainage of periappendiceal abscess, and bladder perforation repair. She died of septic shock on post-operative day 19, due to gross spillage of urine into the abdomen and ongoing necrotizing fasciitis. Acute perforated appendicitis can lead to rare and fatal complications. Our case presents such a patient with a poor outcome. In approaching a patient with signs of peritonitis, differential diagnoses must remain broad to include late complications such as abscess formation, soft tissue infection, and perforation of surrounding structures.

Delayed Bladder Perforation Related to Immediate Single Dose Intravesical Doxorubicin Instillation After TURBT: A Case Report and Literature Review

Introduction

Intravesical chemotherapy instillation immediately after tumor resection is a well-known practice in the management of non-muscle invasive bladder cancer. Despite being largely well tolerated in most cases, it is not devoid of severe and life-threatening complications.

Case Presentation

We present an unusual case of bladder perforation that happened 2 weeks after bladder tumor resection. The patient had received single dose intra-vesical instillation of doxorubicin after TUR-BT. Conservative managements failed to achieve bladder healing; as a result, open surgical repair was performed. To the best of our knowledge, this is the first reported case of bladder perforation after intra-vesical doxorubicin instillation.

Conclusion

The occurrence of such a rare serious complication in a mostly safe intervention must be taken into consideration. A high index of suspicion, timely management, and proceeding to more invasive surgical treatments when necessary are cornerstones in the management and preserving the bladder.

Cystoscopically Guided Repair of a Posterior Perforation of Augmented Bladder

Background: Augmentation cystoplasty for the management of neurogenic bladder is one of the mainstays of pediatric urology. This procedure has multiple well-known complications. The most dangerous of these complications is bladder perforation, which has a mortality rate of 23% to 25% in large part caused by delayed presentation and sepsis. This case report discusses a novel method for identifying the perforation using endourologic techniques to allow for easier repair.

Case Presentation: A 24-year-old woman with a history of spina bifida s/p augmentation cystoplasty with appendicovesicostomy and rectus fascia bladder neck sling 5 years ago presented to the emergency department with a 2-day history of decreased oral intake, nausea, vomiting, fevers, diffuse abdominal pain, and distention. She was found on CT cystogram to have a contrast extravasation from the posterior-dependent portion of the bladder and a large retrovesical fluid collection. On exploratory laparotomy, a leak from the posterior portion of the bladder was confirmed. Owing to the conditions in the abdomen and the patient's obese body habitus, the perforation was very difficult to view. A 17F rigid cystoscope was utilized and the perforation was identified on the posterior inferior portion of the bladder at the anastomotic line. A wire was passed through the perforation into the abdomen where it was seen and an 18F council catheter was then placed in an antegrade manner from the abdomen. Placement of the catheter and inflation of the balloon did not cause any additional apparent damage to the bladder mucosa. With the catheter on traction, the dependent bladder could be pulled back into the operative field, allowing complete observation of the defect for water-tight two-layer closure.

Conclusion: Bladder perforation after augmentation cystoplasty is a potentially life-threatening complication that can be difficult to repair. This article serves to present a novel way to identify and facilitate repair of the defect intraoperatively using endourologic principles for a posterior defect.

The effect of body mass index on retropubic midurethral slings

BACKGROUND

Analyzing surgical databases uses "real-life" outcomes rather than highly selected cases from randomized controlled trials. Retropubic midurethral slings are a highly effective surgical treatment for stress urinary incontinence; however, if modifiable patient characteristics alter outcomes, thereby rendering treatments less effective, patients should be informed and given the opportunity to change that characteristic.

OBJECTIVE

The aim of this study was to evaluate the effect of body mass index on patient-reported outcome measures by analyzing midurethral slings from the British Society of Urogynaecology database.

MATERIALS AND METHODS

The British Society of Urogynaecology approved analysis of 11,859 anonymized midurethral slings from 2007 to 2016. The primary outcome of this retrospective cohort study was to assess how body mass index affects patient-reported outcome measures. Outcomes were assessed at 6 weeks, 3 months, 6 months, or 12 months after surgery, depending on local arrangements. Outcomes were compared by body mass index groups using χ² tests.

RESULTS

As BMI increased, Patient Global Impression of Improvement (PGI-I) scores declined. Women with a normal body mass index (18 to <25) reported feeling better in 91.6% of cases compared to lower rates in BMI groups >30 (87.7-72%) (P < .001). Patient-reported outcome measures for stress urinary incontinence inversely correlated with body mass index, with 97% of women with normal body mass index stating that they were cured/improved compared to women in higher body mass index groups (84-94%) reporting lower rates (P < .005). Patient-reported outcome measures for overactive bladder show that as body mass index increases, patients reported higher rates of worsening symptoms (P < .05). There were higher rates of perforation at the low and high extremes of body mass index.

CONCLUSION

Our results suggest increased body mass index is associated with poorer outcomes after midurethral sling surgery, and that patients should be given the opportunity to change their body mass index. These data could help to develop a model to predict personalized success and complication rates, which may improve shared decision making and give an impetus to modify characteristics to improve outcomes.

Preperitoneal Bladder Augmentation: Feasibility and Results

Introduction:

Bladder augmentation is an important part of pediatric reconstructive urology. This study was conducted to assess the feasibility and results of our technique of preperitoneal bladder augmentation.

Materials and Methods:

Thirty-three children underwent preperitoneal bladder augmentation for small inelastic bladders who had failed medical management or needed undiversion. The underlying diagnosis included neurogenic bladder, valve bladder, bladder exstrophy, non-neurogenic neurogenic, ectopic ureters, and urogenital sinus. The operative procedure involved placing the entire augmentation in the preperitoneal or subcutaneous space after bivalving the native bladder. The augment segment of the bowel with its pedicle was brought into the preperitoneal space through a small opening in the parietal peritoneum. A Mitrofanoff port was also provided where needed.

Results:

Preperitoneal augmentation provided an adequately compliant, good volume bladder except in children with bladder exstrophy or previous abdominal surgery. There was a good cystometric recovery, with resolution of hydronephrosis and incontinence. Vesicoureteral reflux resolved in 24 of 26 units. In the 13 children who were uremic preoperatively, there was a significant decrease in serum creatinine levels, although 9 children continued to have supra-normal serum creatinine. Surgical complications seen were within expectations. There was no incidence of intraperitoneal leak, which is the main projected benefit of this procedure over the traditional “intraperitoneal” method of augmentation.

Conclusions:

The preperitoneal augmentation provides an adequate, safe, and low-pressure reservoir of urine except in cases of bladder exstrophy and previous abdominal surgery.

Destruction of the bladder by single dose Mitomycin C for low-stage transitional cell carcinoma (TCC)--avoidance, recognition, management and consent

OBJECTIVES

To identify a cohort of patients under our care who have had significant and in some cases irreparable damage to their bladders after Mitomycin C (MMC) instillation. To highlight the importance of avoidance and recognition of bladder perforations during transurethral resection of bladder tumour (TURBT) and explore the issue of consent regarding MMC given the serious complications that may occur after its instillation.

PATIENTS AND METHODS

Patients referred to our tertiary centre for a second opinion to manage their complications after a suspected MMC leak was identified from the departmental database between January 2000 and December 2010. After collection of all the records, we established a cohort of six patients. All patients had their initial tumour resection elsewhere and were referred for specialist management thereafter. Details of the operating surgeon and cystoscopic findings were known only in half of the cases. Retrospective analysis of their notes including documentation from the referring centre was undertaken. This included a review of all the histology and imaging.

RESULTS

All patients had immediate severe pelvic pain on instillation of the MMC. Four of the six continue to have chronic pelvic pain. Two patients had urinary retention and three had severe lower urinary tract symptoms. One patient developed a frozen pelvis. Initial treatment was with an indwelling catheter for a period of 2-52 weeks to aid healing. Two patients had reconstructive surgery, one with success and the other with failure, as an intestinal patch failed to close the fistula and he continues with a catheter. One patient had an ileal conduit. No patient was warned of such complications.

CONCLUSIONS

Although rare, prophylactic MMC can have devastating consequences. Patients should be aware of such major risks. Strong emphasis should be placed on the quality of the initial TURBT coupled with the judgement of an experienced surgeon before to MMC instillation. The real clinical benefit could be reviewed and intravesical MMC offered only to patients who have a good chance of benefit.

Conservative treatment of an intraperitoneal bladder perforation

INTRODUCTION

The management of bladder rupture depends on its anatomical location.

MATERIAL AND METHODS

Case report and review of the pertinent English language literature.

RESULTS

A 56-year-old man with history of an anterior rectum resection with partial cystectomy presented with signs of acute renal failure, and later with a tender, distended abdomen. Work-up including serum and ascites biochemistry, cystoscopy, and CT cystography diagnosed urinary ascites. The small intraperitoneal bladder rupture was treated conservatively via continued urinary drainage under urinary antibiotic prophylaxis until closure.

CONCLUSION

A conservative treatment of a small intraperitoneal bladder perforation is possible under certain conditions.

Extraperitoneal urinary bladder perforation detected by FDG PET/CT

Accurate localization of areas of increased metabolic activity on PET only imaging can be challenging. Fusion of PET with CT imaging provides anatomic detail which aids in localization of functional information. As a result, the overall sensitivity and specificity of information provided by PET or CT alone is improved with combined PET/CT resulting in improved diagnosis and patient management. We report a case of an unexpected emergent finding of urinary bladder perforation on PET/CT to stress the importance of accurately interpreting the anatomic and functional data. To our knowledge, diagnosis of bladder perforation on PET/CT has not been previously reported in the literature. Failure to recognize such complications may lead to adverse outcomes.

Pseudo-azotaemia due to intraperitoneal urine leakage: a report of two cases

Ascites, oliguria and increasing serum creatinine levels are often noted in patients with acute kidney injury. However, these presentations are also observed in patients with intraperitoneal urinary leakage. Bladder perforation without obvious trauma is sometimes mistaken for acute kidney injury. We report two cases of bladder perforation resembling acute kidney injury. The first case was a 37-year-old woman with delayed intraperitoneal urinary leakage following total abdominal hysterectomy, and the second was a 70-year-old woman with spontaneous bladder perforation. Although the initial diagnosis in both cases was acute kidney injury, rupture of the urinary bladder was later identified.
