餘尿多少正常？

餘尿多少正常？正常情況下，尿液排空後膀胱中應該沒有或只有非常少量的餘尿。餘尿是指在排尿後仍然殘留在膀胱中的尿液量。

一般來說，成年人的正常餘尿量應該小於50毫升（ml），這個范圍被認為是可接受的。如果餘尿量超過50ml，可能表明存在一些問題。

高餘尿量的常見原因包括：

前列腺問題：前列腺增生、前列腺炎或前列腺癌等前列腺相關問題可能導致尿液排空不完全，增加餘尿量。

膀胱功能障礙：某些疾病或情況，如膀胱肌肉功能障礙、膀胱壁異常、神經性膀胱等，可能導致膀胱無法完全排空，進而產生較高的餘尿。

尿道梗阻：尿道狹窄、結石、腫瘤等尿道梗阻問題可能妨礙正常的尿液流動，導致餘尿的積聚。

一般情況下，餘尿量應該在10毫升（ml）以下。如果餘尿量超過10ml，特別是超過50ml，可能表明存在一些問題。

前列腺相關問題是導致餘尿增加的常見原因之一。例如：

前列腺增生（良性前列腺增生）：隨着年齡的增長，前列腺可能會逐漸增大，壓迫尿道，導致尿液流動受阻。這可能導致排尿不完全和餘尿增加。

前列腺炎：前列腺炎是前列腺組織的炎症，可能由細菌感染或非細菌性原因引起。前列腺炎可以導致尿液排空不完全和餘尿增加。

如果你懷疑自己有高餘尿量的問題，尤其是與前列腺有關，建議咨詢醫生進行評估。醫生可以通過檢查餘尿量、進行前列腺特定的檢查（如直腸檢查和前列腺特異性抗原（PSA）血液檢查）等，來確定餘尿的原因，並制定適當的治療方案。

如果你懷疑自己有高餘尿量的問題，建議咨詢醫生進行評估。醫生可以通過檢查餘尿量，進行膀胱超聲或其他相關檢查，來確定餘尿的原因，並制定適當的治療方案。

How much residual urine is normal? Normally, there should be no or very little residual urine in the bladder after emptying the bladder. Residual urine is the amount of urine that remains in the bladder after urination.

Generally speaking, the normal residual urine volume of an adult should be less than 50 milliliters (ml), and this range is considered acceptable. If the residual urine volume exceeds 50ml, it may indicate some problems.

Common causes of high residual urine volume include:

Prostate problems: Prostate-related problems such as benign prostatic hyperplasia, prostatitis, or prostate cancer can lead to incomplete emptying of urine and increased residual urine volume.

Bladder dysfunction: Certain diseases or conditions, such as bladder muscle dysfunction, bladder wall abnormalities, neuropathic bladder, etc., can cause the bladder to not empty completely, resulting in a high residual urine output.

Urethral obstruction: Urethral obstruction problems such as urethral strictures, stones, and tumors can prevent the normal flow of urine, resulting in the accumulation of residual urine.

Under normal circumstances, the residual urine volume should be below 10 milliliters (ml). Www.poxet.tw If the residual urine volume exceeds 10ml, especially more than 50ml, it may indicate some problems.

Prostate-related problems are one of the common causes of increased residual urine. For example:

BPH (benign prostatic hyperplasia): As you age, the prostate gland may gradually enlarge, compressing the urethra, causing obstruction to the flow of urine. This can lead to incomplete urination and increased residual urine.

Prostatitis: Prostatitis is inflammation of the prostate tissue and can be caused by bacterial infection or nonbacterial causes. Prostatitis can lead to incomplete voiding and increased residual urine.

If you suspect that you have a problem with high residual urine volume, especially related to the prostate, it is recommended to consult a doctor for evaluation. Doctors can determine the cause of residual urine and prescribe appropriate treatment by checking the amount of residual urine and performing prostate-specific tests such as rectal exams and prostate-specific antigen (PSA) blood tests.

If you suspect that you have a problem with high residual urine volume, it is recommended to consult a doctor for evaluation. Doctors can determine the cause of residual urine by checking the residual urine volume, performing bladder ultrasound or other relevant tests, and formulate an appropriate treatment plan.
