Vertical and medial nephroptosis was assessed on 60 consecutive excretory urographic examinations. Ptosis, both vertical and medial, was seen more commonly in females, and vertical ptosis was more frequent than medial ptosis. In our series there was no significant evidence of predominance on the right side. Dietl crisis, nausea, vomiting, hypotension, oliguria, or orthostatic hypertension were not encountered. Nephroptosis was mostly asymptomatic. In those patients with symptoms, lumbar pain was common and could be either aggravated or relieved by change in position. A new sign, paradoxic displacement, is described. This could be of value to the surgeon and radiotherapist in evaluating enlargement of a huge abdominal mass - a difficulat task to assess clinically.

Nephroptosis is a benign disorder defined as a significant descent of the affected kidney as the patient moves from supine to erect. Patients with nephroptosis sometimes manifest symptoms including abdominal pain, back pain, nausea and hematuria, while the majority of those are asymptomatic. Downward migration of the affected kidney induced by a postural change from the supine to the upright position underlies the pathophysiology of nephroptosis. The diagnosis of nephroptosis is difficult since routine imaging examinations are conducted in the supine position alone. Here, we report a case presenting recurrent abdominal pain due to unknown causes. This patient was successfully diagnosed as nephroptosis by ultrasonography and drip infusion pyelography, both of which were performed in both supine and upright positions. This case report strongly suggests that we need to take into consideration a possibility of nephroptosis when we encounter with patients complaining abdominal and/or back pain due to unknown causes.

A 77-year-old woman presented with right flank pain radiating to the ipsilateral groin and associated nausea, consistent with renal colic. In the emergency department, a non-contrast CT scan revealed severe right-sided hydronephrosis but failed to demonstrate a calculus or ureteropelvic obstruction. The patient improved with fluids and followed up with a community urologist. Initial work-up with cystoscopy and ureteroscopy, voiding cystourethrogram and diuretic renography failed to deduce a diagnosis. At our hospital, we used a modified dynamic (supine and upright) Whitaker test in a novel fashion to diagnose nephroptosis, a rare hypermobility condition of the kidney.
