Gossypiboma—Retained Surgical Sponge

Intra-abdominal retained surgical sponge is an uncommon surgical error. Herein, we report a 92-year-old woman who was brought to the emergency room for acute urinary retention. She had a history of vaginal hysterectomy for uterine prolapse 18 years previously, performed at our hospital. Retained surgical sponge in the pelvic cavity was suspected by abdominal computed tomography. The surgical gauze was removed by laparotomy excision and the final diagnosis was gossypiboma.

The gender difference and mortality-to-incidence ratio relate to health care disparities in bladder cancer: National estimates from 33 countries

The variation in the mortality-to-incidence ratio (MIR) between countries and genders reflects the complex etiology and intervention of bladder cancer. In this study, we investigated the MIR variation between genders and health care disparities among countries. Cancer incidence and mortality were obtained from the GLOBOCAN 2012 database. The ranking and the total expenditure on health of countries were obtained from the World Health Organization. Linear regression was used to estimate the significance between variables. We estimated the role of MIRs from 33 countries. Bladder cancer incidence and mortality rates were higher in more developed regions, Europe, and the Americas. The MIRs were higher in less developed regions. Analysis according to country revealed Germany to have the lowest MIR. High relative MIRs (female MIR/male MIR) for bladder cancer were noted in many developed countries. A correlation between MIR and health care disparities among countries was indicated by a significant association between the World Health Organization ranking and total expenditure on health/GDP with the MIR and relative MIR. Low bladder cancer MIR is prone to be more prevalent in countries with good health care system.

Foreign body in the ureter: a particle of glue after transarterial embolization of a renal pseudoaneurysm during percutaneous nephrostomy.

Reports on foreign bodies within the ureter are extremely rare in the literature. Herein, we present a case of a foreign body in a ureter, specifically a particle of glue resulting from transarterial embolization of a renal pseudoaneurysm secondary to percutaneous nephrostomy. Emergent transarterial embolization was required due to life-threatening active bleeding of the pseudoaneurysm. However, the glue material subsequently fell into the ureter where it became a foreign body, resulting in obstructive uropathy. Several surgical interventions, including endoscopic and laparoscopic methods, were performed to retrieve the foreign body, but these attempts were unsuccessful. Finally, the glue material was spontaneously passed out by chance. To the best of our knowledge, this type of complication (a glue particle left over from an embolization procedure migrating into the urinary collecting system) has never been reported. We recommend close follow-up examinations after transarterial embolization for renal pseudoaneurysm in order to avoid possible obstructive uropathy caused by glue materials or coils.

Favorable mortality-to-incidence ratios of kidney Cancer are associated with advanced health care systems

BackgroundThe advancements in cancer therapy have improved the clinical outcomes of cancer patients in recent decades. However, advanced cancer therapy is expensive and requires good health care systems. For kidney cancer, no studies have yet established an association between clinical outcome and health care disparities.MethodsWe used the mortality-to-incidence ratio (MIR) for kidney cancer as a marker of clinical outcome to compare World Health Organization (WHO) country rankings and total expenditures on health/gross domestic product (e/GDP) using linear regression analyses.ResultsWe included 57 countries based on data from the GLOBOCAN 2012 database. We found that more highly developed regions have higher crude and age-standardized rates of kidney cancer incidence and mortality, but a lower MIR, when compared to less developed regions. North America has the highest crude rates of incidence, but the lowest MIRs, whereas Africa has the highest MIRs. Furthermore, favorable MIRs are correlated with countries with good WHO rankings and high e/GDP expenditures (p < 0.001 and p = 0.013, respectively).ConclusionsKidney cancer MIRs are positively associated with the ranking of health care systems and health care expenditures.
