Nephrectomy Care: the nurse's role, start to finish
Written and reviewed by Dana Whitfield, RN, MSN · 5 min read · Updated September 2026
Short answer
Nephrectomy care centres on protecting the remaining kidney: urine output under 30 mL an hour signals inadequate perfusion or obstruction and must be reported at once. Pre-op work covers baseline renal function and cross-matched blood; post-op, the flank dressing is checked for bleeding every time the patient is turned, alongside pain control and early mobilisation.
What the procedure achieves
A nephrectomy removes all or part of a kidney, most often for renal cell carcinoma, a non-functioning kidney from chronic obstruction or infection, or as a living donor procedure. Partial nephrectomy spares functioning tissue when the tumour is small and peripheral; radical nephrectomy removes the whole kidney, and sometimes the adrenal gland and surrounding lymph nodes, when disease is more extensive.
The approach shapes recovery. A laparoscopic or robotic nephrectomy leaves small port-site incisions and a shorter stay. An open flank incision, still used for large tumours or complex anatomy, cuts through muscle and carries more post-op pain and a longer recovery. Either way, the patient is left with one kidney doing the work of two, which is the fact that drives almost every nursing decision that follows.
Pre-procedure nursing responsibilities
Baseline renal function comes first: serum creatinine, eGFR, and BUN, drawn before any nephrotoxic contrast or medication is given. A CT or MRI has usually already confirmed the diagnosis and mapped the vasculature, so the nurse's job is to confirm it's been reviewed and consent reflects the planned extent of resection, since partial can become radical intra-operatively.
Cross-matched blood is held on standby given the vascularity of the kidney and its major vessels. Baseline vital signs, weight, and a bowel prep if ordered round out preparation, along with routine pre-op fasting and anticoagulant review. Teach the patient to expect a flank or abdominal dressing, one or more drains, and possibly a urinary catheter on waking, so nothing post-op comes as a surprise.
Equipment and positioning
Intra-operatively the patient is placed in a lateral decubitus position with the table flexed to open the space between the ribs and iliac crest, exposing the flank. This position risks pressure injury and brachial plexus stretch, so padding at the axilla, hips, and bony prominences is standard, and positioning is documented.
On return to the ward or recovery unit, expect an indwelling urinary catheter to allow accurate hourly output measurement, a surgical drain near the renal bed, and often a peripheral or central line for fluid replacement. IV fluids are titrated to keep the remaining kidney well perfused, and a patient-controlled analgesia pump is common after an open approach given the incision's proximity to respiratory muscles.
Complications and early signs
The number that matters is urine output under 30 mL an hour from the remaining kidney. Sustained low output signals hypoperfusion, hypovolaemia, or acute kidney injury in the solitary kidney and warrants immediate escalation rather than a wait-and-see approach, since this kidney has no partner to compensate.
The flank dressing is checked for bleeding every time the patient is turned or repositioned, since retroperitoneal haemorrhage can pool silently before it's visible on the dressing itself. Watch drain output for a sudden increase or a change from serosanguinous to frank blood. Other early warning signs include falling blood pressure with rising heart rate, flank or shoulder-tip pain suggesting diaphragmatic irritation, and reduced bowel sounds from post-op ileus, which is common after retroperitoneal surgery.
Post-procedure care
Hourly urine output and vital signs are the backbone of the first 24 hours. Pain is managed proactively, since shallow breathing from unrelieved flank pain increases the risk of atelectasis and pneumonia, particularly after an open incision. Incentive spirometry and early, assisted mobilisation are started as soon as haemodynamically stable, usually within the first day.
Drains are monitored for volume and character and removed once output tails off, typically over several days. Diet progresses from clear fluids once bowel sounds return, and the catheter usually comes out once the patient is mobile and output is reliably measured without it. Renal function bloods are repeated to confirm the remaining kidney is compensating adequately before discharge is considered.
What to teach before discharge
Patients need to understand that nephrotoxic drugs, including many NSAIDs and some contrast agents, now carry more weight and should be flagged to any future prescriber. Adequate hydration protects the solitary kidney, and they should know the signs of dehydration and reduced output to watch for at home.
Wound and drain-site care, activity restrictions such as avoiding heavy lifting for several weeks, and when to resume driving are covered before discharge. Teach them to report fever, increasing flank pain, wound discharge, or a marked drop in urine output promptly rather than waiting for a follow-up appointment. A clear schedule for repeat bloods and imaging, where relevant to the underlying diagnosis, closes out the teaching.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our renal and genitourinary practice questions are the closest set to what this page covers.
Common questions
What urine output is concerning after a nephrectomy?
Output under 30 mL an hour from the remaining kidney is the threshold that prompts escalation. Because the patient now relies on a single kidney, sustained low output can mean hypoperfusion, hypovolaemia, or early acute kidney injury and should not be left to self-resolve.
How often should the flank dressing be checked after nephrectomy?
Check it every time the patient is turned or repositioned, not just at set intervals, since retroperitoneal bleeding can accumulate before it soaks through visibly. Pair dressing checks with drain output and vital sign trends for the full picture.
Why is positioning during nephrectomy surgery a nursing concern?
The lateral decubitus position with the table flexed opens the flank for surgical access but stretches the brachial plexus and loads pressure points at the axilla and hips. Padding and documentation of positioning are standard precautions against nerve injury and pressure sores.
What NCLEX-style priority applies immediately after nephrectomy?
Hourly urine output monitoring from the remaining kidney is typically the highest priority in the immediate post-op period, above pain control and mobility, because it's the earliest indicator of a threat to the only functioning kidney.
Can a patient live normally with one kidney after nephrectomy?
Yes, a single healthy kidney can sustain normal renal function for most people, but it has no reserve if injured. That's why lifelong avoidance of unnecessary nephrotoxic drugs and attention to hydration are part of discharge teaching.
