EC Clinical and Medical Case Reports

The patient was 34 years old and was admitted to the urology department for febrile pelvic pain associated with functional disorders such as pollakiuria and dysuria. Two months earlier, he had been hospitalised and treated for acute prostatitis. At that time, a pelvic ultrasound scan showed the absence of the right kidney and a prostatic abscess in the presence of a hypoechoic, well-limited image in the prostatic cavity with a volume of 250 cm³. A puncture was performed and the cytobacteriological study of the fluid collected revealed Escherichia coli. The examination during this second admission revealed, apart from the fever, an extremely painful rectal touch and pain in the hypogastrium. The rest of the examination was unremarkable. Ultrasound and uroscanner showed images suggestive of a clean-walled retrovesical cystic mass, pushing the bladder forward and to the left, a single left kidney in compensatory hypertrophy (Figure 1). The extraperitoneal approach is carried out through an iliac incision, allowing the individualisation of a cystic formation, the dissection of which is extremely difficult due to the numerous adhesions to the bladder but especially to the prostate.
