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).
This page describes our tours along the Weser River. The Weser is one of the longest rivers in western Germany behind the Rhine. Formed by the confluence of the Werra and Fulda at Hanoverische MÃ¼nden, it flows over 450 kilometers north into the North Sea.
