The main planet responsible for diseases relating to kidney is Venus. With this, Moon should be also taken into account. The houses related in a natal chart are the sixth and seventh houses. In the Zodiac, the corresponding signs involved are Virgo and Libra. Therefore, any affliction by malefics like Mars, Saturn, Rahu or Ketu on Venus and/or Moon, the sixth and/or seventh house of the natal chart and/or their lords as well as the signs Virgo and/or Libra may result in kidney troubles. The Ascendant and its lord should also be taken into account as a strong Ascendant or lord thereof may overcome many troubles. The benefic influence of Jupiter may also cause some relief.
