Tenesmus

Tenesmus may refer to:

• Rectal tenesmus – a clinical symptom, where there is a feeling of constantly needing to pass stools, despite an empty colon. When the word "tenesmus" is used by itself, this is usually what is meant.
• Vesical tenesmus – a clinical symptom, where there is a feeling of constantly needing to urinate, despite an empty bladder.
