Composition and histopathological features of prostatic calculi in patients with benign prostatic hyperplasia / 中华男科学杂志

Objective@#To analyze the composition of prostatic calculus in patients with BPH and explore its pathogenic factors and histopathological characteristics.@*METHODS@#Strictly following the inclusion and exclusion criteria, we included in this retrospective study 580 cases of bipolar transurethral plasma kinetic prostatectomy (TUPKP) performed in our hospital from May 2015 to May 2019, analyzed the histopathological and calculus-composition features of the patients with BPH complicated by prostatic calculi (the BPH+PC group) and the histopathological data of those with BPH only (the BPH group). We compared the related factors between the two groups of patients and performed uni- and multivariate logistic regression analyses of the data on those in the BPH+PC group.@*RESULTS@#The incidence rate of chronic inflammation was significantly higher in the BPH+PC than in the BPH group (83.1% vs 61.1%, P 0.05). Logistic regression analyses showed that prostatic calculus was significantly correlated with chronic inflammation of the prostate, the patient's age and IPSS (P 0.05).@*CONCLUSIONS@#Prostatic calculus has a high incidence in BPH patients and varies widely in composition, chiefly consisting of calcium oxalate and carbonate apatite. The major factors contributing to prostatic calculi include chronic inflammation of the prostate (primarily the severe type), age and BPH. Prostate calculi may aggravate lower urinary tract symptoms, especially urinary storage symptoms, in patients with BPH, but not significantly affect the PSA level.？.

Laparoscopic adrenalectomy:a report of 21 cases / 中国基层医药

Objective To investigate the clinical application of laparoscopic adrenalectomy and summarize the experience in laparoscopie adrenalectomy.Methods From August 2002 to March 2007,21 cases of benign adrenal tumors were treated with retroperitoneal laparoscopy in this hospital.There were 9 cases of adrenocortical adenoma, 7 cases of primary aldosteronism,3 cases of adenocorticol macronodular hyperplasia,1 case of pheochromccytoma,and 1 case of adrenal gangliocytoma.Results Retroperitoneal laparoscopy was successfully applied in 21 cases.Operating time was between 65 and 130min with an average of 95 min.All patients did not receive blood transfusion and had no obvious complications.Conclusion Laparoscopic adrenalectomy had the advantages of minimal morbidity,mini- mal postoperative discomfort and a short hospital stay,whieh had a good prospect for application in the clinical prac- tice.
