According to specialized literature, prostatic calculi are found in up to 80 % of men over the age of 50. Prostatic calculi associated with chronic prostatitis may be closely related to lower urinary tract symptoms and may cause nonspecific symptoms of LUTS. The treatment approaches of prostatic calculi in chronic prostatitis include drug therapy, minimally invasive and open surgeries, the number of which is actually decreasing worldwide. This phenomenon is mostly related to the emergence of both new diagnostic technologies and endourological treatment. The study included 30 patients with bladder outlet obstruction caused by prostatic calculi due to CNBP, who were diagnosed via a series of clinical and paraclinical investigations.
