Hydronephrosis
Definition
- Hydronephrosis is a condition where one or both kidneys swell due to the accumulation of urine.
Causes
- Ureteropelvic junction obstruction (UPJO)
- Ureterovesical junction obstruction (UVJO)
- Congenital anomalies
- Infections
- Tumors
- Trauma
- Benign prostatic hyperplasia (BPH)
Pathology and Progression
- The renal pelvis and calyces become distended with urine.
- The renal parenchyma compresses and atrophies.
- Chronic obstruction can lead to permanent damage and scarring.
Clinical Features
- Abdominal pain
- Nausea and vomiting
- Hematuria
- Pyelonephritis
- Chronic kidney disease
Diagnostic Approach using Imaging
- Ultrasonography
- Computed tomography (CT) scan
- Intravenous pyelography (IVP)
- Magnetic resonance imaging (MRI)
Management Strategies
- Conservative management
- Ureteral stenting
- Nephrostomy tube placement
- Pyeloplasty
- Ureteral reimplantation
- Nephrectomy
Types of Hydronephrosis
- Acute hydronephrosis
- Chronic hydronephrosis
- Recurrent hydronephrosis
Pathophysiology
- The kidney's ability to concentrate urine is compromised.
- The renal pelvis and calyces become distended.
- The renal parenchyma compresses and atrophies.
Complications
- Chronic kidney disease
- Pyelonephritis
- Urosepsis
- Renal failure
Treatment
- Conservative management: bed rest, analgesics, and hydration.
- Ureteral stenting: to relieve obstruction.
- Nephrostomy tube placement: to drain the kidney.
- Pyeloplasty: surgical repair of the ureteropelvic junction.
- Ureteral reimplantation: surgical repair of the ureterovesical junction.
- Nephrectomy: surgical removal of the kidney.
Homoeopathic Therapeutic Medicines
- Lycopodium: for renal colic and hydronephrosis.
- Berberis: for renal colic and urolithiasis.
- Cantharis: for urinary retention and hydronephrosis.
- Apis: for renal inflammation and hydronephrosis.
- Pulsatilla: for renal colic and hydronephrosis.
Blood Supply
- The blood supply to the kidney is primarily through the renal arteries.
- The renal arteries arise from the abdominal aorta.
- The renal arteries divide into segmental arteries.
Nerve Supply
- The nerve supply to the kidney is primarily through the renal plexus.
- The renal plexus is a network of nerves that surrounds the kidney.
- The renal plexus receives input from the sympathetic and parasympathetic nervous systems.
Clinical Anatomy
- The kidney is located in the retroperitoneal space.
- The kidney is surrounded by the renal fascia.
- The renal fascia is a fibrous layer that surrounds the kidney.
- The renal fascia is continuous with the peritoneum.
