Brief summary

Anterior lumbar spinal surgery involves making an incision through the abdomen of the patient in order to access the spine. During this process, several internal structures are pushed aside in order to gain access. One of these structures is the ureter, whose function is to drain urine from the kidney to the bladder. One potential complication that can arise from this is dilation of the kidney - known as hydronephrosis. The aim of this study is to identify whether hydronephrosis after Anterior Lumbar Interbody Fusion (ALIF) is complication, in order to bring this to the attention of health care professionals when considering this kind of surgery.

Detailed description

A total of 40 patients who have had ALIF surgery will be invited to have an ultrasound scan of their kidney on the side where the operation was performed (where the scar is). Should hydronephrosis of this kidney be detected, the investigators will go on to scan the second kidney. Should hydronephrosis be detected the patient will be given a letter to take to their General Practitioner (GP) advising them to be referred to a Urologist.

Interventions

RADIATIONUltrasound

Single ultrasound scan of kidney on side of body where ALIF was performed. If hydronephrosis of this kidney is detected, the second kidney will also be scanned.
