We report 2 cases of inguinoscrotal hernias involving urologic organs. The first case involved an elderly gentleman with a history of micturition by squeezing his scrotum. He was diagnosed as having a right-sided indirect inguinal hernia involving the right ureter and bladder. Treatment was surgical. The second case involved an achondroplastic male who presented with acute kidney injury. He had bilateral hydronephrosis and ureteric obstruction secondary to an ureteroinguinal herniation bilaterally. The presentation, diagnosis, and treatment of inguinoscrotal hernias involving the bladder and ureters are discussed.
Introduction: Most small renal masses (SRMs) are diagnosed incidentally and have a low malignant potential. As more elderly patients and infirm patients are diagnosed with SRMs, there is an increased interest in active surveillance (AS) with delayed intervention. Patient and tumour characteristics relating to aggressive disease have not been well-studied. The objective was to determine predictors of growth of SRMs treated with AS. Methods: A multicentre prospective phase 2 clinical trial was conducted on 207 SRMs in 169 patients in 8 institutions in Canada from 2004 to 2009; in these patients treatment was delayed until disease progression. Patient and tumour characteristics were evaluated to determine predictors of growth of SRMs by measuring rates of change in growth (on imaging) over time. All patients underwent AS for presumed renal cell carcinoma (RCC) based on diagnostic imaging. We used the following factors to develop a predictive model of tumour growth with binary recursive partitioning analysis: patient characteristics (age, symptoms at diagnosis) and tumour characteristics (consistency [solid vs. cystic] and maximum diameter at diagnosis. Results: With a median follow-up of 603 days, 169 patients (with 207 SRMs) were followed prospectively. Age, symptoms at diagnosis, tumour consistency and maximum diameter of the renal mass were not predictors of growth. This cohort was limited by lack of availability of patient and tumour characteristics, such as sex, degree of endophytic component and tumour location. Conclusion: Slow growth rates and the low malignant potential of SRMs have led to AS as a treatment option in the elderly and infirm population. In a large prospective cohort, we have shown that age, symptoms, tumour consistency and maximum diameter of the mass at diagnosis are not predictors of growth of T1a lesions. More knowledge on predictors of growth of SRMs is needed.
Background: Acute reversible kidney injury (ARKI) secondary to bilateral ureteric obstruction (BUO) is a common urological problem. Our goals were to describe the etiology, management and outcomes of such patients identified between 2006 and 2009 and to compare them with a similar historical study published in 1982. Methods: Chart review was performed on 49 patients with AKRI secondary to BUO. ARKI was defined as ≥33% decrease in serum creatinine after intervention. Those with malignant and benign causes of obstruction were identified and management and outcome data were collected. Results: Of these 49 patients, 83% had BUO secondary to malignancy, 28% of these presenting for the first time. Prevalence of bladder cancer was increased (p = 0.04) and cervix trended lower (p = 0.07) compared with the earlier study; prostate cancer was unchanged (p = 0.51). The average survival was 239 days; 90% of patients died within a year after presenting with BUO from a malignant etiology. Compared with the 1982 group, there were trends towards a decrease in the frequency of retroperitoneal fibrosis (p = 0.08) and an increase in bilateral ureteric calculi (p = 0.16) in the benign group. Conclusions: Patients with ARKI secondary to BUO most likely have an underlying malignancy, with almost a third of them being diagnosed for the first time. Prevalence of bladder cancer increased while cervical cancer trended lower. The cause for the former is unclear; the latter may be due to aggressive screening. Prostate cancer remained unchanged despite the widespread implementation of prostate-specific antigen testing. Patients with an underlying malignancy do poorly and those with a newly diagnosed malignancy do worst. Those with ARKI secondary to benign causes did well.
Burkholderia cepacia infection of the prostate is very rare. Wereport 6 cases of prostatic infection secondary to inoculation ofcontaminated ultrasound gel during transrectal biopsy of the prostate.All of these patients required hospitalization and were treatedwith intravenous antibiotics. One of these cases is the first descriptionof chronic prostatitis with B. cepacia.
We have observed that intermittent ADT in patients with CRPCa, using a testosterone of >1.75 ngmol/L as a trigger to reinitiate LHRHa, results in a substantial cost savings with no negative impact on oncologic and QOL outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
