Significant variations of urinary pH can cause problems for all human beings, but these problems are magnified when an individual has a urostomy. Most significant stomal and peristomal complications are related to an alkaline urine including hyperkeratosis; stoma bleeding, incrustation, and ulceration; stoma stenosis; urinary tract infection; odor; and urinary calculi. Treatment of these conditions includes both external and internal measures. External methods of treatment involve keeping urine away from the stoma and the peristomal skin by use of a correctly fitting clean appliance and a night drainage system. Vinegar solution compresses can help to restore the acid mantle of the skin. Internal methods of treatment that are advocated in the literature include ingestion of cranberry juice and ascorbic acid to promote urine acidity. Increasing oral intake of fluids is the least risky method to promote the production of acidic, dilute urine, and results are equally effective.
尿液pH值的显著变化会给所有人带来问题，但当个体进行了尿路造口术时，这些问题会被放大。大多数严重的造口和造口周围并发症都与碱性尿液有关，包括角化过度；造口出血、结痂和溃疡；造口狭窄；尿路感染；异味；以及尿路结石。这些病症的治疗包括外部和内部措施。外部治疗方法包括使用合适的清洁器具和夜间引流系统，使尿液远离造口和造口周围皮肤。醋溶液湿敷有助于恢复皮肤的酸性保护膜。文献中提倡的内部治疗方法包括摄入蔓越莓汁和抗坏血酸以促进尿液酸化。增加口服液体摄入量是促进产生酸性、稀释尿液风险最小的方法，且效果同样显著。
