A pure leiomyoma of the prostate is a rare tumor. Less than 30 cases about prostatic leiomyoma have been reported. Pathologic anatomy examination is the only medium for definitive diagnosis and is important to rule out malignancies such as leiomyosarcoma. We describe an accidental finding of a tumor in the right prostate lobe of a 54 year old man, who was diagnosed with prostatic leiomyoma and treated with open radical prostatectomy.
Objective: The efficacy of intravesical chemotherapy in abolishing small papillary recurrences of non-muscle-invasive bladder cancer (NMIBC), the disease-free interval in responders and patients' preferences were explored. Methods: When a small (≤1 cm) papillary recurrence of a NMIBC was diagnosed, the patient could choose between immediate transurethral resection of the bladder (TURB) or four weekly intravesical instillations with mitomycin C (MMC) or epirubicin (ERC). Control cystoscopy was scheduled 2-3 weeks after the last instillation. Complete remission was defined as total disappearance of all papillary tumours and negative cytology. Results: 25 patients with 47 recurrence episodes were recruited from February 2003 until August 2011. The median follow-up was 35 months. After exclusion of 2 patients with intolerance to the instillations, 45 study episodes could be analysed. All patients to whom this was proposed preferred the instillations over immediate TURB. Complete, partial and no response was seen in 23 (51%), 6 (13%) and 16 (36%) out of 45 episodes, respectively. The median disease-free interval after complete remission was 16 months (95% confidence interval 9-24). Conclusions: Small papillary recurrences of NMIBC completely disappear in about half of the cases receiving four weekly bladder instillations with MMC or ERC. This is followed by a disease-free interval. Intravesical chemotherapy was preferred by all patients over immediate TURB.
This was a retrospective, descriptive, cross-sectional study performed at Groote Schuur Hospital (GSH), Cape Town, South Africa. During the study period (1 January 2009 to Background: The standard of care for surgically resectable disease renal cell carcinoma (RCC) is a nephrectomy. Post nephrectomy, these patients are at risk for the development of new onset chronic kidney disease or the progression of pre-existing chronic kidney disease. We aimed to report the changes in renal function in patients who had a nephrectomy for RCC. Methods: This retrospective, descriptive, cross-sectional study identified 137 patients who had a nephrectomy for RCC from 1 January 2009 to 31 December 2017. The pre-nephrectomy and post-nephrectomy estimated glomerular filtration rate (eGFR) and the histological subtype of RCC on histopathological analysis of the resected specimen were recorded from the National Health Laboratory Services online results platform. All analyses were conducted using SPSS (Version 25) and the significance level was set at p < 0.05. Results: After a mean follow-up period of 26.5 ± 22 months (median = 19 months), the patients' eGFR dropped by a mean of 4.82 ± 8.67 ml/min/1.73 m 2 (95% CI 3.23-6.41) post-nephrectomy. The mean eGFR fall in patients' who had hypertension and/or diabetes (n = 63) was significantly larger compared to patients who had neither of these comorbidities (n = 54; p < .001; mean = 7.30 ± 8.40 ml/min/1.73 m 2 (95% CI 5.19-9.42) and 1.93 ± 8.14 ml/min/1.73 m 2 (95% CI 0.30-4.15) respectively. Conclusions: The decline in renal function in patients with hypertension and/or diabetes mellitus is more pronounced than in patients with neither of these comorbidities. In these high-risk patients, measures must be taken to prevent the development and limit the progression of chronic kidney disease.
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.
