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).
The shape of the Rhine delta is determined by two bifurcations: first, at Millingen aan de Rijn, the Rhine splits into Waal and Pannerdens Kanaal, which changes its name to Nederrijn at Angeren, and second near Arnhem, the IJssel branches off from the Nederrijn.ear Tamins-Reichenau the Anterior Rhine and the Posterior Rhine join and form the Alpine Rhine. The river makes a distinctive turn to the north near Chur. This section is nearly 86 km long, and descends from a height of 599 m to 396 m. It flows through a wide glacial alpine valley known as the Rhine Valley.
