Main Symptoms of Neurogenic Bladder

Neurogenic bladder means the nerves that talk to the bladder are off-line, so the organ can’t fill, store, or empty like it should. The result is a mix of leaks, floods, and leftover urine. Urgency floods are common. A sudden “gotta go” hits and you may leak before reaching the toilet, or the bladder empties completely without warning. Retention shows the other side. You feel full but only dribble, or need to push or catheterize to get urine out. Frequency climbs. Because the bladder never fully empties, it refills fast—hourly trips day and night. Leakage between voids is typical. Small... Learn more

Main Symptoms of Testicular Torsion

Testicular torsion happens when the spermatic cord twists, cutting off blood to the testicle. It strikes fast—often in the middle of the night or after a minor bump—and is a true emergency. Sudden, severe pain is the hallmark. It feels like someone kicked the ball and the ache keeps climbing, usually on one side only. Swelling is quick. The scrotum puffs within minutes and looks red or purple. The testicle rides high. One ball hangs sideways or tilts like a bell clapper and can’t be eased down. Nausea and vomiting ride along. The pain triggers a sick stomach and can... Learn more

Main Symptoms of Urinary System Tumors

Urinary-system tumors can start in the kidney, ureter, bladder, prostate, or urethra. Most grow quietly at first, so blood in the urine or stubborn pee changes are often the first clues that something is growing where it shouldn’t. Painless blood is the red flag. Urine may turn pink, tea-brown, or contain small clots, and it often looks clear between episodes. Stream changes follow. The flow becomes thin, forked, stops and starts, or drips long after you think you’re done. Urgency and frequency climb. You dash every hour, yet only a small amount comes out each time. Obstruction pain shows up.... Learn more

Main Symptoms of Genitourinary Tuberculosis

Genitourinary tuberculosis happens when TB bacteria settle in the kidneys, bladder, or prostate. The infection moves slowly, so early clues are easy to blame on a plain bladder infection—until they don’t go away. The first hint is burning that lingers. Urination stings at the start and keeps smoldering, even after several courses of regular antibiotics. Urgency and frequency climb. You dash every hour, yet only a spoonful comes out, and the urge returns fast. Blood is the red flag. Urine can turn light pink, tea-brown, or contain small clots, often without any pain. Flank or lower-belly ache creeps in. It... Learn more

Main Symptoms of Urinary System Diseases

Urinary system diseases can hit anywhere from the kidneys to the tip of the penis. Most send the same early warnings—burn, blood, and bathroom dashes—so knowing the pattern helps you act fast. Burning is the universal red flag. It stings at the start of the stream, lingers afterward, and can feel like hot sauce on the pee hole. Blood shows up next. Urine may turn pink, tea-brown, or contain small clots, often without any pain. Urgency and frequency team up. You race to the bathroom every hour, yet only a spoonful comes out each time. Flank or lower-belly pain joins... Learn more
