Two types of pain have their origins in the genitourinary organs:

    • Local
    • Referred- more common
  • Local pain
    • is felt in or near the involved organ.
    • the pain from a diseased kidney (T10–12, L1) is felt in the costovertebralangle and in the flank in the region of and below the 12th rib.
  • Referred pain
    • originates in a diseased organ but is felt at some distance from that organ.
    • The ureteralcolic caused by a stone in the upper uretermay be associated with severe pain in the ipsilateraltesticle
ureteral pain
Ureteral pain
  • Ureteralpain is typically stimulated by acute obstruction (passage of a stone or a blood clot)
  • The physician may be able to judge the position of a ureteral stone by the history of pain and the site of referral.
  • If the stone is lodged in the upper ureter, the pain radiates to the testicle, since the nerve supply of this organ is similar to that of the kidney and upper ureter(T11–12).
ureteral pain1
Ureteral pain
  • With stones in the midportion of the ureter on the right side, the pain is referred to McBurney’s point and may therefore simulate appendicitis
  • On the left side, it may resemble diverticulitis or other diseases of the descending or sigmoid colon (T12, L1).
kidney pain
Kidney Pain
  • Typical renal pain is felt as a dull and constant ache in the costovertebral angle just lateral to the sacrospinalis muscle and just below the 12th rib.
  • This pain often spreads along the subcostal area toward the umbilicus or lower abdominal quadrant.
  • It may be expected in the renal diseases that cause sudden distention of the renal capsule.
    • Acute pyelonephritis (with its sudden edema)
    • acute ureteral obstruction (with its sudden renal back pressure)
    • both cause this typical pain.
kidney pain1
Kidney Pain
  • It should be pointed out, however, that many urologic renal diseases are painless because their progression is so slow that sudden capsular distention does not occur.
    • Such diseases include :
      • cancer
      • chronic pyelonephritis
      • staghorncalculus
      • tuberculosis
      • polycystic kidney
      • hydronephrosisdue to chronic ureteral obstruction.
radicular pain
Radicular pain
  • Radicular Pain, or Radiculitis, is pain "radiated" along the dermatome (sensory distribution) of a nerve due to inflammation or other irritation of the nerve root at its connection to the spinal column.
  • Radicular pain is commonly felt in the costovertebral and subcostal areas.
  • It may also spread along the course of the ureter and is the most common cause of so-called “kidney pain.”
radicular pain1
Radicular pain
  • Every patient who complains of flank pain should be examined for evidence of nerve root irritation.
  • Frequent causes are:
    • poor posture (scoliosis, kyphosis)
    • arthritic changes in the costovertebral or costotransversejoints
    • impingement of a rib spur on a subcostalnerve
    • hypertrophy of costovertebral ligaments pressing on a nerve
    • intervertebraldisk disease
radicular pain2
Radicular pain
  • Pain experienced during the preeruptive phase of herpes zoster involving any of the segments between T11 and L2 may simulate pain of renal origin.
  • Radiculitis usually causes hyperesthesia of the area of skin served by the irritated peripheral nerve.
  • This hypersensitivity can be elicited by means of the pinwheel or grasping and pinching both skin and fat of the abdomen and flanks.
  • Pressure exerted by the thumb over the costovertebral joints reveals local tenderness at the point of emergence of the involved nerve.
urinary obstruction
Urinary obstruction
  • Normally, urine is formed in the kidneys, flows through the ureters to the bladder, and is released through the urethra.
  • A urinary obstruction blocks the normal flow of urine, causing it to back up toward the kidneys.
  • Urine flowing the wrong way in the urinary tract can cause infections and kidney damage.
  • Obstruction can occur anywhere in the urinary tract:
urinary obstruction1
Urinary obstruction
  • Because of their damaging effect on renal function, obstruction and stasis of urinary flow are among the most important urologic disorders.
  • Either leads eventually to hydronephrosis, a peculiar type of atrophy of the kidney that may terminate in renal insufficiency or, if unilateral, complete destruction of the organ.
  • Furthermore, obstruction leads to infection, which causes additional damage to the organs involved.
etiology
Etiology

A. CONGENITAL

  • The common sites of congenital narrowing:
    • externalmeatus in boys (meatalstenosis)
    • external urinary meatus in girls
    • the distal urethra (stenosis)
    • posterior urethral valves
    • ectopic ureters
    • ureteroceles
    • ureterovesical and ureteropelvic junctions.
  • Another congenital cause of urinary stasis is damage to sacral roots 2–4 as seen in spina bifida and myelomeningocele.
etiology1
Etiology

B. ACQUIRED

  • Acquired obstructions are numerous and may be primary in the urinary tract or secondary to retroperitoneal lesions that invade or compress the urinary passages.

Among the common causes are:

(1) urethral stricture secondary to infection or injury

(2) benign prostatic hyperplasia or cancer of the prostate

(3) vesical tumor involving the bladder neck or ureteral orifices

(4) local extension of cancer of the prostate or cervix into the base of the bladder

(5) compression of the ureters at the pelvic brim by metastatic nodes from cancer of the prostate or cervix

(6) ureteral stone

(7) retroperitoneal fibrosis or malignant tumor

(8) pregnancy

classification
Classification
  • Obstruction may be classified according to:
    • cause (congenital or acquired)
    • duration (acute or chronic)
    • degree (partial or complete)
    • level (upper or lower urinary tract)
clinical manifestations
Clinical manifestations

Upper tract (ureter and kidney)—

  • Symptoms of obstruction of the upper tract are typified by the symptoms of ureteral stricture or ureteral /renal stone.

The principal complaints are :

  • pain in the flank radiating along the course of the ureter
  • gross total hematuria (from stone)
  • gastrointestinal symptoms
  • chills
  • fever
  • burning on urination
  • cloudy urine with onset of infection
  • Nausea, vomiting, loss of weight and strength, and pallor are due to uremia secondary to bilateral hydronephrosis.
clinical manifestations1
Clinical manifestations
  • Lower urinary tract obstruction (bladder, urethra)
    • can manifest as voiding dysfunction such as
      • urgency
      • frequency
      • nocturia
      • incontinence
      • decreased stream
      • hesitancy
      • postvoid dribbling
      • sensation of inadequate emptying
    • Suprapubicpain or a palpable bladder indicates urinary retention.
    • Infection may be present, and patients may experience dysuria.
    • Hematuriamay be present with or without infection.
clinical manifestaions
Clinical manifestaions

Signs of obstruction in the upper urinary tract:

  • An enlarged kidney may be discovered by palpation or percussion.
  • Renal tenderness may be elicited if infection is present.
  • A large pelvic mass (tumor, pregnancy) can displace and compress the ureters.
  • Children with advanced urinary tract obstruction may develop ascites.
  • Rupture of the renal fornices allows leakage of urine retroperitoneally;with rupture of the bladder, urine may pass into the peritoneal cavity through a tear in the peritoneum.
pathogenesis
Pathogenesis
  • The hallmark of urinary tract obstruction is dilation of the collecting system of the kidney which is known as hydronephrosis.  This swelling typically causes pain in the flank or upper abdomen on the affected side. 
pathogenesis1
Pathogenesis
  • Progressive back pressure on the ureters and kidneys can occur and can cause hydroureter and hydronephrosis. The ureter can then become dilated and tortuous, with the inability to adequately propel urine forward.
  • Chronic urinary tract obstruction can lead to permanent damage to the urinary tract.
  • Infravesicalobstruction can lead to changes in the bladder, such as
    • trabeculation,
    • cellule formation
    • diverticula
    • bladder wall thickening
    • detrusormuscle decompensation
pathogenesis2
Pathogenesis
  • Hydronephrosis can cause permanent nephron damage and renal failure.
  • Urinary stasis along any portion of the urinary tract increases the risk of stone formation and infection, and, ultimately, upper urinary tract injury.
  • Urinary tract obstruction can cause long-lasting effects to the physiology of the kidney, including its ability to concentrate urine.
