Intractable hiccup due to giant hydronephrosis: A rare case report and literature review

INTRODUCTION: Giant hydronephrosis (GH) is a rare disease that is found in adult patients. Although there are some common symptoms associated with hydronephrosis, such as surrounding organ compressed, its rarer symptoms can render diagnosis very difficult, and treatment should also vary according to the cause. PRESENTATION OF CASE: We here report an 82-year-old man who was admitted to the hospital for repeated intractable hiccups. After B-ultrasound and CT examination, the patient underwent laparoscopy surgery, which was converted to open nephrectomy, and the patient’s intractable hiccup symptoms disappeared. DISCUSSION: GH is a rare disease, and its symptoms are diverse. The more unusual symptoms of cystic hypertonic compression of surrounding organs, such as intractable hiccups, should be taken into account. GH is mainly diagnosed via ultrasound examination and CT scan. The choice of treatment for GH needs to be based on the etiology and renal function of hydronephrosis, and consider malignant lesions. CONCLUSION: Giant hydronephrosis can present rare symptoms as “intractable hiccups”. The selection of treatment should be made depending on the cause.
