All the patients were treated using a Direx Integra lithotripter, with the number of shockwaves ranging from 1200 to 3500, without anaesthesia and were discharged a few hours after the procedure on the same day. In a majority (63.75%) of the cases, the calculi were incidental findings. A Double-J stent was indicated in two patients and preceded extracorporeal lithotripsy because of renal colic and signs of urinary tract infection. <strong>Results:</strong> We recruited a total of 122 patients with a mean age of 42.19 ± 13.08. We had 65 (53.3%) males and all patients had at least one calculus confirmed by CT scan with a mean size of 13.84 ± 4.17 mm, 85 (69.7%) patients became completely stone-free after a maximum of four sessions of extracorporeal lithotripsy (ESWL). 21 (17.2%) patients had intermediate results, being asymptomatic and/or having less than three residual fragments that measured less than 4 mm. The failure rate was 13.9%, with 17 patients still having more than three fragments measuring more than 4 mm after 4 ESWL sessions. 1 (0.8%) had septic shock as a post ESWL complication while 6 (4.9%) benefitted from a complimentary medical and/or surgical treatment (double J stent placement). <strong>Conclusion:</strong> The management of renal and ureteral calculi through extracorporeal lithotripsy in adults seems to be particularly effective for renal calculi measuring less than 20 mm and ureteral calculi measuring less than 15 mm. Extracorporeal lithotripsy, which can be performed on an outpatient basis (and without anaesthesia) is associated with minimal complications, and remains the option of choice for most upper urinary tract calculi.展开更多

This paper aims to describe the epidemiological, clinical, diagnostic, therapeutic, and evolutionary aspects of patients with early metastatic prostate cancer in a urology center in the city of Douala in Cameroon. <strong>Materials and Methods:</strong> It is a retrospective and descriptive study of 110 patients with prostate cancer that was immediately metastatic at diagnosis over a period of six years (from January 2014 to December 2020). <strong>Results:</strong> The average age of patients at diagnosis was 67.5 years (range: 45 years to 88 years) and 53.63% of patients had body mass indexes greater than 25. Disorders of the lower urinary tract were the main presenting complaint in 55.45% of cases, followed by bone and joint pain in 46.36% of cases. Digital rectal examination was suggestive of prostate cancer in 96.36% of cases with an average total prostatic specific antigen (PSAT) level of 676.9 ng/ml (range: 21.8 to 8832 ng/ml). The diagnosis was made through prostate biopsy in 57 (51.81%) patients or after palliative endoscopic resection of the prostate indicated for lower urinary tract symptoms or even acute urinary retention in 53 (48.18%) patients. Adenocarcinoma of the prostate was the main histologic type, and in 47.27% of cases, the tumor was poorly differentiated with a Gleason’s score of greater than 7. The sites of metastasis were mainly the lymph node (87.27%), bone (56.36%), and both (44.54%). The treatment was palliative and dominated by bilateral pulpectomy in 60% of cases and luteinizing hormone-releasing hormone agonists (Triptorelin 11.25 mg every 3 months) in 44 (40%) of cases. <strong>Conclusion:</strong> Prostate cancer is a real public health problem in developed countries but also in Africa, especially in Cameroon. It is aggressive cancer that is often diagnosed when metastasis has already occurred. Its management is essentially palliative.展开更多
