[Male genitourinary ultrasound studies (MGUUS) (author's transl)].

The authors report their experience of male genitourinary ultrasound studies of the anterior pelvis over a period of 4 years and involving almost 500 patients. The authors first used a classical ultrasound apparatus in real-time via an anterior abdominal approach. They now have an Aloka mode B apparatus in real-time which by use of three approaches (anterior abdominal, rectal and urethral) offers the possibility of analysis of the male anterior pelvis with four planes of section: 1 sagittal and 3 transverse. Thus MGUUS provides 12 views of the male pelvis. The authors define the techniques used in the light of their experience with this apparatus. They then describe the normal ultrasound anatomy of the male anterior pelvis. Finally, they present their results in pathology with this technique. These results have been obtained in benign and malignant prostatic pathology, everyday routine, longitudinal analyses before and after treatment: surgery, radiotherapy and medical. The results are promising in more recent indications: tumours of the bladder, endocrine andrology, pathology of fertility and in the investigation of the pathological scrotum. Implantation of MGUUS at the centre of technical approaches in urology is felt by the authors to be a necessity, making possible the rational and economic use of the apparatus for both in- and out-patients and the cost of an ultrasound apparatus for every hospital department of urology would appear to be reasonable.
