[Ashthila (hard globular swelling like tumor)] When vata obstructs the path of mutra, it causes adhmana (distension) of basti (bladder area) and guda (rectal area) producing ashthila (stone like hard mass or swelling) which is chala (freely mobile), unnata (elevated) which causes tivra arti (severe pain) and vinmutrarodhini (obstruction to stools and urine).

[Vatabasti (vata affliction of bladder)] Withholding the urine in the basti causes vata to aggravate which causes mutrarodha (urinary obstruction), arti (pain), kandu (itching) and this is called vatabasti.
[Ushnavata ((vata-pitta affliction of urine/burning micturition)] Due to indulgence in ushma (factors that increase the heat in the body), there will be mutra shosha (decrease in mutra), raktapita mutra (reddish or yellowish urine), passed with difficulty (krichchrat), causing arti (pain) and daha (burning) in basti (urinary bladder) and upastha (genitalia). This is ushnavata.

[Vatakundalika (scanty and painful flow of urine)] Due to gatisanga (obstruction in the pathway) of mutra in the mutrasthana (mutrasaya) and mutramarga (mutravaha srotas), the viguna vayu (aggravated vata) becomes udavratta (reflux or moves in opposite direction) and thereby bhagna (broken), vyaviddha (zigzag) or kundali (rotatory) in its pathway.
It then affects the mutra with samstambha (stiffness or rigidity), bhanga (breaking pain), gaurava (heaviness), veshtana (twisting pain), tivraruk (severe pain) and mutravitsanga (retention of urine and feces). The condition is called vata kundalika.
