A retrospective case-control study (1990-1995), the Berlin Urothelial Cancer Study (BUS), examined analgesics and laxatives as risks for the induction of urothelial cancer in renal pelvis, ureter and bladder. Especially for renal pelvis cancer could observe substance and dose specific risk of compound analgesics. The analgesic substances Phenacetin, Paracetamol, Acetylsalicylic acid (ASA) and Pyrazolones were assessed. Besides a risk of contact laxatives (chemical or anthranoide ingredients) for urothelial cancer was found, not yet described. The highest risk shows the anthranoide plant Senna. Thus this study confirms the risk of specific analgesic ingredients and found an evidence for a new risk of contact laxatives. As both, analgesics and contact laxatives, are typical OTC--("Over the counter") products, a severe controlling is demanded and for laxatives further studies are needed.

In 85% of patients, renal colic is caused by renal-ureteral stones with extrinsic obstructions such as pelvic, retroperitoneal or intestinal abnormalities, and intrinsic reno-ureteral obstructions, e.g. junction pathologies and malformation, accounting for only 10 and 5%, respectively. The objectives of therapy for renal colic therapy are to eliminate pain, preserve renal function and eliminate the obstruction by the excretory pathway. Many drugs can be used to relieve pain: non-steroid anti-inflammatory agents (NSAIDs), opioid analgesics, antidiuretic hormone (ADH), loco-regional anesthesia and acupuncture. Opiates are the first-choice therapy during pregnancy as no other drug is indicated because of tetragenic potential. Paracetamol (N-acetyl-p-aminophenol) is the only NSAID that is registered for pediatric use because it has none of the adverse side effects that are associated with NSAIDs. Tamsulosin, an alpha-lithic drug, has very recently been included among the drugs that are used for stone expulsion. The rationale underlying its use is that a high concentration of alpha-1D adrenergic receptors has been recently detected in the terminal ureter, especially in the intramural tract. Inhibition of alpha-1D receptor stimulation should relax smooth muscle in the intramural ureteral tract, making stone expulsion easier.
