title: [Retroperitoneoscopic nephropexy].
abstract: BACKGROUND
  Nephroptosis has been defined as renal descent of 5 or more cm on orthostasis. This disease is more frequent in young and slim women. The patient complains pain in upright position,that regress lying down. The therapy consists of surgical treatment. We report the case of a woman treated with retroperitoneoscopic nephropexy.
  
  
  METHODS
  We present the case of a 25-years old woman, affected by lumbar pain in upright position for about 1 year. Ultrasound scan of the abdomen and RX-KUB did not show hydronephrosis nor stones. Both an orthopedic examination and a spinal MRI excluded bone or muscular diseases. Intravenous pyelography and diuretic isotope renography in upright position revealed a renal descent of more than 5 cm, without obstruction of upper urinary tract. The patient underwent a renal color doppler imaging, that showed reduction of right kidney resistive index in upright position. The patient underwent a right retroperitoneoscopic nephropexy. After complete dissection of the perirenal fat from the kidney, three nonabsorbable sutures were placed between the posterior renal capsule and the psoas muscle.
  
  
  RESULTS
  No blood loss nor peri-operative complications have been observed. One month after the procedure, the patient did not complain any pain. Renal color doppler, performed one month after the nephropexy, showed a normalization of resistive index.
  
  
  CONCLUSIONS
  Symptomatic nephroptosis is a disease that has been questioned in the past. Nowadays, the modern imaging and functional examination available allow to identify the “true”cases of symptomatic nephroptosis. The treatment with retroperitoneoscopic nephropexy is an easy and effective procedure.
