The following symptoms and complaints may indicate obstructive uropathy or refluxuropathy (urinary transport disorder/urinary retention):
- Feeling of pressure in the area of the kidney or kidney pain due to urinary retention.
- Colicky pain / ureteral pain (ureteral pain), nausea (nausea), hematuria (blood in the urine) – in kidney stone or ureteral stone (ureteral stone).
- Fatigue, fever, signs of inflammation in infectious renal congestion.
Kidney pain
Renal colic is caused by acute stretching of the renal capsule. Because they project to the costovertebral (rib-vertebra) angle (here also: tenderness) below the 12th rib, they are often mistaken for back pain. Because of gastrointestinal accompanying symptoms of renal colic, diseases of intraperitoneal organs must be differentiated. Differential diagnoses:
- Pancreatitis (inflammation of the pancreas) or perforated duodenal ulcer (“perforated” duodenal ulcer); main pain radiates in the epigastrium (abdominal region between the costal arch and the navel) and into the back. Patients often adopt a protective posture.
- Irritation of the costovertebral nerves Th 10-12; pain is usually movement-dependent.
Note: Slow-onset and progressive (increasing) urinary transport disorders (e.g., due to tumor disease) result in asymptomatic urinary stasis kidneys.
Ureteral Pain
Ureteral colic results from distension (expansion or over-expansion), hyperperistalsis (increased activity), and spasm (spasm) of the ureteral smooth muscle (ureteral muscle). The symptoms depend on the location of the obstruction (closure):
- Causes in the middle third of the ureter (ureteric third) → pain radiating to the lower abdominal quadrants (differential diagnoses: left diverticulitis (inflammation of the wall of the diverticulum; right acute appendicitis (appendicitis)).
- Concrements in the intramural (“in the organ wall”) ureter → irritative micturition complaints (discomfort during urination) and pain radiation in labia (labia), scrotum (scrotum) and tip of the penis.
- Prevesical (“before the bladder“) stones or bladder stones typically cause bladder irritation symptoms. Patients complain of dysuria (difficult, volitional emptying of the bladder (micturition), which may be additionally painful) and pollakiuria (urge to urinate frequently without increased urination).
