Abstract Background The angiogenesis inhibitor monoclonal antibody Bevacizumab is presently the standard treatment for numerous neoplasms but particular toxicities are emerging, such as hypertension, haemorrhage, thromboembolism, gastrointestinal perforation, fistulae, and delayed wound healing. The addition of Bevacizumab to radio and chemotherapy has improved the overall survival rate in patients with metastatic, persistent or recurrent cervical carcinoma. However an increased risk of enteric or urinary fistula formation has been documented, related to hypoxia which is induced by the inhibition of angiogenesis. Moreover, previous pelvic surgery, repeated ureteral stenting and radiation are additional risk factors. Case presentation We describe the remarkable case of a right ureteral stent displacement inside the rectum lumen in a patient treated with Bevacizumab for pelvic recurrence of cervical cancer. The patient was referred to our Urology Department with urinary sepsis and bilateral hydronephrosis. Right ureteral stent substitution was planned; at cystoscopy the distal loop of the stent was not visualized inside the bladder. The presence of the distal loop of the right ureteral inside the rectum was clearly demonstrated with a CT scan. Conclusions Since Bevacizumab is increasingly used in the treatment of gynaecological neoplasms and indwelling ureteral stents are often required to treat or prevent ureteral compressions, similar cases are likely to be diagnosed and this complication should be considered in the management of advanced pelvic cancers.

The Difference

AbstractAlthough many ureteral stents are commercially available, the actuality of encrustation is yet to be elucidated in humans. This study compared the Tria Ureteral Stent with PercuShield and the Polaris Ultra Ureteral Stent with HydroPlus Coating for short-term encrustation formation. Eighty-four patients, who required ureteral stent placement after ureteroscopy, were randomized into two stent groups. After stent removal on postoperative day 14, the encrustation volume on the stent surface was measured by micro-computed tomography. The primary outcome was the inner luminal encrustation volume. Secondary outcomes were encrustation volume on the outer or total surfaces and occurrence of adverse events. Clinical factors related to encrustation were also assessed as a post-hoc analysis. Finally, of the 82 patients analyzed, 75 (91.5%) had encrustation in the inner lumen of the stent. The difference in median inner encrustation volume between the Tria and Polaris Ultra stents was comparable (0.56 vs. 0.37 mm3, P = 0.183). There was no difference observed in the encrustation volume on the outer/total surfaces and stent-related adverse events. In both ureteral stents, the shaft body showed significant inner luminal encrustation compared to the proximal or distal loop (all, P < 0.05). Dyslipidemia (P = 0.027), elevated urine pH (P = 0.046), and crystalluria (P = 0.010) were associated with encrustation formation. The Tria and Polaris Ultra stents had similar efficacy for preventing encrustation in the short-term. Further studies are required to compare their long-term patency.

The new artificial pancreas system includes a body-attached blood glucose sensor that tracks glucose levels, a worn insulin infusion pump that communicates with the sensor, and features new software that integrates the two systems. The artificial pancreas is purportedly revolutionary because of its closed-loop design, which means that the machine can give insulin without direct patient intervention. It can read a blood sugar and administer insulin based on an algorithm. But, the hardware for the corporate artificial pancreas is expensive and its software code is closed-access. Yet, well-educated, tech-savvy diabetics have been fashioning their own fully automated do-it-yourself (DIY) artificial pancreases for years, relying on small-scale manufacturing, open-source software, and inventive repurposing of corporate hardware. In this chapter, we trace the corporate and DIY artificial pancreases as they grapple with issues of design and accessibility in a content where not everyone can become a diabetic cyborg. The corporate artificial pancreas offers the cyborg low levels of agency and no ownership and control over his or her own data; it also requires access to health insurance in order to procure and use the technology. The DIY artificial pancreas offers patients a more robust of agency but also requires high levels of intellectual capital to hack the devices and make the system work safely. We argue that efforts to increase agency, radically democratize biotechnology, and expand information ownership in the DIY movement are characterized by ideologies and social inequalities that also define corporate pathways.
