My mother aged 85 is having hypothyroidism, allergic bronchitis, hiatal hernia, oesophageal ulcers, urinary incontinence and dementia. She's bed-bound since past 2 and a half years. She has had hematuria episodes within a span of 10 days. She has been treated with antibiotics. Usg kub shows post void volume of more than 500 cc. Her kft and cbc is normal. Abdominal ct scan shows that her bladder wall is trabeculated and having diverticula. Is there any alternative apart from catheterization? Currently she has to wear diapers as she's bed bound. She's on a course of macpee 25 mg, 3 tabs/day, veltam 0.4 ,1 tab, niftas 100 mg 1 tab per day. She sometimes complains of lower abdominal pain, her spo2 levels and pulse shows fluctuation. Pulse today reached 128 .this happens sometimes. She has never had such fluctuations before. Can it be because of her medications for urinary retention? Surprisingly, her urine routine (sample collected using a catheter) shows 75-80 pus cells but culture is negative, no growth seen. U please advise .she has completed almost 25-28 days course of the meds for urinary retention and uti.
