Dysuria is an extremely common symptom in women, but it can occur in men and can occur at any age. Dysuria results from irritation of the bladder trigone or urethra. Inflammation or stricture of the urethra causes difficulty in starting urination and burning on urination. Irritation of the trigone causes bladder contraction, leading to frequent and painful urination. Dysuria most frequently results from an infection in the lower urinary tract, but it could also be caused by an upper UTI. Impaired renal concentrating ability is the main reason for frequent urination in upper UTIs.
En route, the Rhine lives up to its Celtic name near Schaffhausen, when it plunges 75 feet down in a spectacular torrent known as the Rheinfall. Its waters are much calmer at Basel, where the river first becomes navigable (and where many cruise ships embark).
With the junction of the Main River at Mainz, in Germany, the Rhine's seasonal regime becomes more stabilized. Along its course from Bingen to Bonn is a beautiful stretch of the Rhine Valley. The river has cut the deep, steepsided Rhine Gorge through the Rhineland Plateau and the Rhenish Slate Mountains.ast of Frankfurt is where The Rhine-Main-Danube Canal links the Rhine with the Danube River, providing a transcontinental route from the North Sea to the Black Sea near Odessa, Ukraine. During early historic times, Germanic tribes settled on either side of the lower Rhine and Celts alongside its upper sides.
