It has been reported that some patients have been misdiagnosed with Nephrolithiasis, when in fact the correct diagnosis in their specific case was Pelvic Inflammatory Disease.
Pelvic inflammatory disease is an infection of the uterus and symptoms include, pain in your lower abdomen, fever, unusual discharge with a bad odour, pain and or bleeding with sex, burning sensation with urination and bleeding in-between periods. PID can be misdiagnosed as conditions like appendicitis, ectopic pregnancy, diverticulitis, adnexal torsion (twisted ovary), rupture of an ovarian cyst, kidney stones, pancreatitis and perforated viscus (hole in the bowl). If misdiagnosed and not treated correctly issues like scar tissue can form inside and outside the fallopian tubes that can lead to tubal blockage, ectopic pregnancy (pregnancy outside of the womb), infertility and long term pelvic pain.
