Renal Transplantation is the surgical placement of a healthy donor kidney into a patient with end-stage renal disease (ESRD) to restore normal kidney function.
It is considered the treatment of choice for patients with chronic kidney failure.
β βRenal transplant is a definitive treatment for ESRD involving implantation of a functional donor kidney into a recipient to replace lost renal function.β
π II. Types of Renal Transplant
Type
Description
Living Donor Transplant
Kidney donated by a living person (related/unrelated).
Deceased Donor Transplant
Kidney obtained from a brain-dead individual.
Preemptive Transplant
Performed before dialysis starts.
π III. Indications
End-stage renal disease (GFR <15 ml/min)
Chronic kidney disease not responding to medical management
Conditions like:
Diabetic nephropathy
Hypertensive nephrosclerosis
Polycystic kidney disease
Glomerulonephritis
Reflux nephropathy
π IV. Contraindications
Active infection
Untreated malignancy
Severe cardiovascular disease
Non-adherence to medical therapy
Psychological instability
HIV/AIDS (in some cases)
π V. Preoperative Evaluation
Blood group and tissue typing (HLA typing)
Crossmatch testing (to detect rejection risk)
Screening for infections (Hepatitis B/C, HIV, TB)
Renal imaging studies
Assessment of cardiac and respiratory fitness
Psychosocial evaluation
π VI. Surgical Procedure (In Brief)
Performed under general anesthesia.
Donor kidney is usually placed in iliac fossa (lower abdomen).
Renal artery and vein are connected to iliac vessels.
Ureter is connected to the bladder.
Native kidneys are usually not removed unless needed.
π VII. Postoperative Management
Monitor for graft function (urine output, serum creatinine).
Drug side effects (nephrotoxicity, diabetes, hypertension)
π IX. Nursing Responsibilities
Monitor vitals, fluid balance, and renal function.
Strict aseptic technique to prevent infection.
Educate on immunosuppressive therapy adherence.
Watch for signs of rejection and infection.
Support psychological and emotional well-being.
Counsel on lifestyle modifications (diet, hydration, hygiene).
π Golden One-Liners for Quick Revision:
Renal transplant is preferred over lifelong dialysis in eligible patients.
Tacrolimus and Mycophenolate are common immunosuppressive drugs.
HLA mismatch increases risk of rejection.
Graft tenderness + decreased urine output indicates possible rejection.
Native kidneys are usually left intact unless infected or malignant.

β I. Introduction / Definition
Neurogenic bladder is a dysfunction of the urinary bladder caused by neurological damage, leading to problems with storing or emptying urine.
It may cause urinary retention, incontinence, or frequent urinary tract infections (UTIs).
β βNeurogenic bladder is a condition where nerve damage impairs bladder control, resulting in abnormal bladder function such as overactivity or underactivity.β
π II. Types of Neurogenic Bladder
Type
Description
Spastic (Hyperreflexic)
Bladder contracts too often; seen in upper motor neuron lesions.
Flaccid (Areflexic)
Bladder does not contract; seen in lower motor neuron lesions.
Mixed Type
Alternating spastic and flaccid behavior.
π III. Causes / Risk Factors
Spinal cord injury (SCI)
Multiple sclerosis (MS)
Diabetes mellitus (diabetic neuropathy)
Stroke
Parkinsonβs disease
Spina bifida
Tumors affecting the spinal cord or brain
Pelvic surgery with nerve injury
π IV. Pathophysiology (In Brief)
Damage to nerves controlling bladder muscles.
Disruption of the normal bladder-emptying reflex.
Either detrusor overactivity or underactivity.
Results in incontinence, urinary retention, and increased risk of UTI.
π V. Clinical Manifestations
Urinary urgency and frequency
Incontinence (leakage of urine)
Difficulty starting urination
Weak or interrupted stream
Retention of urine
Recurrent urinary tract infections
Overflow dribbling
π VI. Diagnostic Evaluation
Urinalysis and urine culture β detect infections
Post-void residual (PVR) urine volume β using ultrasound or catheterization
Urodynamic studies β assess bladder pressure and capacity
Cystoscopy β visual examination of bladder
MRI or CT scan β to identify neurological causes
