Plain-language summary

The purpose of the study is to investigate the impact of ureteral stents on the functioning of ureteral peristalsis (normal contractions in the ureteral organ muscle).

Inclusion criteria

✓. stone disease
✓. localized tumor disease
✓. hydronephrosis of unknown ethiology
✓. patients who receive a prophylactic stent before a planned operation.

Exclusion criteria

✕. Patients being septic and in a life-threatening condition before or after stent-insertion
✕. patients with tumors in a progressive state that affect the retroperitoneum (contralateral ureter might be affected and can not serve as a control for the stented side)
✕. patients with Morbus Ormond (same reason as above)
✕. patients requiring ureteral stents bilaterally (same reason as above)
✕. long-term stented patients will be excluded as we are interested in evaluating the onset of changes in peristalsis rate which are expected to be most significant in an acute setting.
✕. patients with preexisting abnormalities/pathologies of the urinary tract e.g. reflux disease, megaureter or bladder dysfunctions as these will likely affect our results
✕. non English-speaking patients will be excluded as they will not be able to understand the letter of consents.
✕. known preexisting pathology in the urinary tract (see above)
