Distal ureteral stenosis after early adjuvant intravesical mitomycin C application for superficial bladder cancer

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.

[Superficial bladder cancer: Transurethral resection and instillation therapy]

Bladder cancer is the fifth most common tumor in men with the incidence of bladder tumors continuing to rise in industrialized and developed countries. Because 80% of all bladder tumors grow on the surface, endoscopic transurethral resection (TUR-B) can be used for complete removal. Due to continuous technical developments and improvements of endoscopic equipment, video imaging and bipolar resection (TUR-IS) offers a high level of safety. Despite optimal equipment, intra- and postoperative complications in transurethral electrosurgery of bladder tumors may occur.

Distal ureteral stricture: An unexpected complication of further adjuvant intravesical mitomycin C thermotherapy

We present a case of distal ureteral obstruction in relation to further adjuvant intravesical thermochemotherapy with mitomycin C (MMC) for non-muscle invasive bladder cancer (NMIBC). We also discuss the diagnostic procedures and management of this recurrent case.

Complications associated with single-dose, perioperative mitomycin-C for patients undergoing bladder tumor resection

OBJECTIVES

To better understand the risk of short-term complications associated with perioperative intravesical mitomycin-C (MMC) therapy for patients undergoing endoscopic management of non-muscle invasive bladder cancer.

METHODS AND MATERIALS

Using an institutional database of patients with bladder cancer, we performed a retrospective case-control study of patients receiving perioperative MMC after tumor resection (2008-2012). MMC cases were matched by clinical stage to controls receiving endoscopic resection alone. Demographic information, clinicopathologic details, and outcomes were compared between groups. Outcomes of interest included overall, genitourinary, and major complications. Chi-square tests and multivariable logistic regression were used to evaluate associations among patient characteristics, clinical factors, exposure to MMC, and outcomes of interest.

RESULTS

One-hundred sixteen patients treated with MMC were matched to 116 controls. Patients receiving MMC were younger (P = 0.04) and more likely to have invasive disease (i.e. T1 or greater) (23% vs. 15%, P = 0.02). Complications were more frequent among patients who were treated with MMC (34.5% vs. 19.8%, Odds Ratio 2.89, 95% Confidence Interval 1.43-5.81). The most common complication among MMC patients that required medical management was dysuria (17%). Major complications were more common among MMC patients (5.2% vs. 0.9%), but this difference did not reach statistical significance (P = 0.11).

CONCLUSIONS

Use of MMC is associated with a greater odds of complications compared with controls. Patients should be counseled regarding both the benefits and potential risks of perioperative intravesical MMC. Continued research is required to understand the safety implications associated with the use of perioperative, intravesical MMC.

Intravesical mitomycin C for superficial transitional cell carcinoma

Intravesical instillation of mitomycin C after a transurethral resection of a bladder tumor constitutes a standard treatment modality in the management of superficial transitional cell carcinoma in the urinary bladder. An immediate instillation of mitomycin C after transurethral resection has been shown to reduce the recurrence rate of superficial transitional cell carcinoma. Intravesical mitomycin C is generally considered to be a safe treatment option, but the past few years have seen the publication of a number of case reports on severe complications following mitomycin C instillation. This article reports on the mode of action, as well as the intravesical effects and current indications for mitomycin C instillation. This review will summarize the oncological benefits of mitomycin C in comparison with other intravesical treatments, such as bacillus Calmette-Guérin, and elucidate the incidence and types of possible complications associated with intravesical mitomycin C chemotherapy.

Low-grade Ta (noninvasive) urothelial carcinoma of the bladder

This article discusses the development of international guidelines for the diagnosis, treatment, follow-up, and prevention of low-grade Ta urothelial carcinoma of the bladder. The authors, who are experts in this field from 3 continents and 7 countries, reviewed the English language literature through September 2004. The results of the authors' deliberations are presented here as a consensus document. The objective of this study was to determine the optimal diagnostic workup, treatment, follow-up, and prevention of low-grade, Ta urothelial carcinoma of the bladder. A consensus conference convened by the World Health Organization (WHO) and the Société Internationale d'Urologie (SIU) met to critically review the literature on the diagnosis and treatment of low-grade Ta urothelial carcinoma of the bladder. Research was conducted using Medline; this search engine also was used to identify additional works not detected at the initial search. Evidence-based recommendations for diagnosis and management of the disease were made with reference to a 4-point scale. Low-grade Ta urothelial carcinoma of the bladder is a well-studied subject with many level 1 and 2 evidence references that support clinical practice. Findings from 135 reviewed citations are summarized. Many grade A and B recommendations on the diagnostic workup and management of this disease can be given with level 1 and 2 evidence based on prospective randomized clinical trials of sufficient statistical power. This should improve the quality of the treatment of this disease.
