"Based on advances in research and clinical practice, and major shifts in social attitudes and in relevant policies, laws, and human rights standards", the World Health Organization (18 June 2018) removed Fetishism, Transvestic Fetishism and Sadomasochism as psychiatric diagnoses.The ICD-11 classification consider Sadomasochism as a variant in sexual arousal and private behavior without appreciable public health impact and for which treatment is neither indicated nor sought. "Further the ICD-11 guidelines "respect the rights of individuals whose atypical sexual behavior is consensual and not harmful. "WHOs ICD-11 Working Group admits that psychiatric diagnoses have been used to harass, silence, or imprison sadomasochists. Labeling them as such may create harm, convey social judgment, and exacerbate existing stigma and violence to individuals so labeled.According to ICD-11, psychiatric diagnoses can no longer be used to discriminate against BDSM people and fetishists.Recent surveys on the spread of BDSM fantasies and practices show strong variations in the range of their results. Nonetheless, researchers assume that 5 to 25 percent of the population practices sexual behavior related to pain or dominance and submission. The population with related fantasies is believed to be even larger. Forensic classification
According to Anil Aggrawal, in forensic science, levels of sexual sadism and masochism are classified as follows:
Sexual masochists:

Class I: Bothered by, but not seeking out, fantasies. May be preponderantly sadists with minimal masochistic tendencies or non-sadomasochistic with minimal masochistic tendencies
Class II: Equal mix of sadistic and masochistic tendencies. Like to receive pain but also like to be dominant partner (in this case, sadists).
Renal colic is a type of abdominal pain commonly caused by obstruction of ureter from dislodged kidney stones. The most frequent site of obstruction is the vesico-ureteric junction (VUJ), the narrowest point of the upper urinary tract. Acute obstruction and the resultant urinary stasis (disruption of urine flow) can distend the ureter (hydroureter) and cause a reflexive peristaltic smooth muscle spasm, which leads to a very intense visceral pain transmitted via the ureteric plexus. Signs and symptoms
Renal colic typically begins in the flank and often radiates to below the ribs or the groin. It typically comes in waves due to ureteric peristalsis, but may be constant. It is often described as one of the most severe pains.Although this condition can be very painful, most ureteric stones under 5 mm size will eventually pass into the bladder without needing treatments, and cause no permanent physical damage. The experience is said to be traumatizing due to the severe pain, and the experience of passing blood and clots as well as pieces of stone. In most cases, people with renal colic are advised to drink more water to facilitate passing; in other instances, lithotripsy or endoscopic surgery may be needed. Preventive treatment can be instituted to minimize the likelihood of recurrence. Diagnosis
The diagnosis of renal colic is the same as the diagnosis for renal calculus and ureteric stones.
