Urinary retention - Nursing Case Study

Pathophysiology

• Primary mechanism: Obstruction of the urinary tract, often due to an enlarged prostate in men or urethral stricture, leads to difficulty in urine flow, causing retention.

• Secondary mechanism: Detrusor muscle dysfunction, where the bladder muscle becomes weak or loses coordination, hinders effective bladder emptying and contributes to retention.

• Key complication: Chronic urinary retention can lead to bladder damage, infections, and increased risk of kidney impairment due to prolonged pressure buildup.

Section 1

Initial Assessment Findings:

Upon the initial nursing assessment, the 45-year-old male patient presents with a distended bladder, palpable upon abdominal examination, which correlates with his complaint of lower abdominal discomfort. The patient reports a frequent urge to urinate, but he is unable to initiate or maintain a urine stream. He describes the sensation as "pressure-like" rather than sharp pain. No fever is noted, and his vital signs remain stable, with a blood pressure of 120/80 mmHg, heart rate of 78 bpm, respiratory rate of 16 breaths per minute, and temperature of 98.6°F. The patient is alert and oriented, demonstrating no signs of acute distress beyond the urinary symptoms.

The nursing team conducts a bladder scan, which reveals a post-void residual volume of approximately 600 mL, confirming significant urinary retention. Routine urinalysis is ordered to check for any signs of infection or hematuria, given the patient's history of benign prostatic hyperplasia (BPH). The nurse notes that the patient is currently taking Tamsulosin, a medication aimed at relaxing the muscles in the prostate and bladder neck to improve urine flow, but it appears to be insufficient in managing his symptoms effectively today.

Given these assessment findings, the nursing team recognizes the need to address the urinary retention promptly to prevent further complications. An indwelling urinary catheter may be considered to relieve the acute retention and monitor urine output. The team will also need to evaluate the effectiveness of the current medication regimen and consider possible adjustments in collaboration with the healthcare provider. Further diagnostic testing, such as imaging or urodynamic studies, may be warranted if the retention persists or recurs, to better understand the underlying cause and guide long-term management strategies. The case will be closely monitored for any changes in the patient's condition or the development of new symptoms.

Response to Interventions:

Following the initial assessment, the nursing team proceeds to insert an indwelling urinary catheter to relieve the patient's acute urinary retention. The procedure is successful, and approximately 800 mL of clear, yellow urine is immediately drained from the bladder. The patient reports a significant decrease in lower abdominal discomfort and expresses relief from the previous sensation of pressure. This intervention allows the nursing team to accurately monitor urine output and assess the patient's renal function.

Post-catheterization, the patient's vital signs remain stable, with blood pressure continuing at 120/80 mmHg, heart rate at 76 bpm, respiratory rate at 16 breaths per minute, and temperature steady at 98.6°F. A follow-up urinalysis returns with no signs of infection or hematuria, indicating that the urinary retention was likely mechanical in nature due to the patient's BPH. The nursing team discusses the findings with the healthcare provider, who suggests an adjustment in the patient's medication regimen to better manage his symptoms long-term. The provider decides to increase the dosage of Tamsulosin while considering the addition of Finasteride to further reduce prostate size and improve urine flow.

The patient is educated on the importance of adhering to the adjusted medication regimen and monitoring for any recurrence of symptoms. He is advised to report any changes such as increased difficulty in urination, new onset of pain, or signs of infection such as fever or chills. The nursing team schedules a follow-up appointment to reassess the patient's condition and evaluate the effectiveness of the medication changes. The patient is also informed about the possibility of further diagnostic testing if symptoms persist or worsen, to ensure comprehensive management of his BPH and prevent future episodes of urinary retention.

Three days after the initial intervention and medication adjustment, the patient returns for his follow-up appointment. During this visit, the nursing team conducts a thorough reassessment of his condition. The patient reports feeling generally well, with no recurrence of the acute urinary retention symptoms he previously experienced. He mentions being able to urinate more freely, although he still experiences a slightly weak stream at times. The patient's adherence to the medication regimen is confirmed, and he reports no adverse effects from the increased dosage of Tamsulosin or the addition of Finasteride.

During the physical assessment, the patient's vital signs remain stable: blood pressure is 118/78 mmHg, heart rate is 72 bpm, respiratory rate is 16 breaths per minute, and temperature is 98.4°F. A bladder scan is performed, revealing a post-void residual urine volume of 75 mL, which is within the normal range and suggests improved bladder emptying. Urinalysis is repeated, and the results continue to show no signs of infection or hematuria, confirming the absence of any acute urinary complications.

Given the current findings, the healthcare provider is pleased with the patient's progress and advises the continuation of the current medication regimen. The nursing team reinforces the importance of regular follow-up visits to monitor the patient's condition and adjust treatment as necessary. The patient is encouraged to maintain fluid intake and is provided with education on lifestyle modifications that may further alleviate BPH symptoms, such as reducing caffeine and alcohol consumption. The successful response to interventions thus far sets a positive trajectory for the patient's ongoing management of BPH and prevention of future urinary retention episodes.

A month later, the patient returns for another follow-up appointment. During this visit, he reports feeling generally well but mentions experiencing occasional nocturia, waking up once or twice per night to urinate. He also notes a slight increase in the frequency of urination during the day but denies any pain or discomfort. He continues to adhere to his medication regimen and has implemented recommended lifestyle modifications, including reducing caffeine intake. The patient expresses mild concern about the nocturia but is otherwise satisfied with the improvement in his symptoms.

The nursing team conducts a thorough physical assessment. The patient's vital signs remain stable, with a blood pressure of 120/80 mmHg, heart rate of 70 bpm, respiratory rate of 16 breaths per minute, and temperature of 98.6°F. A bladder scan once again shows a post-void residual urine volume of 80 mL, consistent with previous findings and indicating continued effective bladder emptying. A repeat urinalysis remains clear, with no signs of infection or blood, reinforcing the absence of acute complications.

Given the current assessment, the healthcare provider reassures the patient that occasional nocturia and increased frequency are common with BPH and can be managed with ongoing lifestyle adjustments and medication. The patient is encouraged to continue monitoring his fluid intake and to avoid drinking large amounts of fluid in the evening. The team schedules another follow-up appointment in three months to ensure continued progress and address any emerging concerns. This structured approach aims to maintain the patient's comfort and prevent any further episodes of urinary retention.

Three months later, the patient returns for his scheduled follow-up appointment. During this visit, he reports that his nocturia has slightly worsened, with him now waking up three to four times per night to urinate. While he continues to experience increased daytime frequency, he still denies any pain, discomfort, or urgency. His adherence to the medication regimen remains consistent, and he has made further lifestyle adjustments, such as limiting evening fluid intake. Despite these efforts, he expresses growing concern about the impact of nocturia on his sleep quality and daily functioning.

The nursing team conducts another detailed physical assessment. The patient's vital signs remain stable, with a blood pressure of 118/78 mmHg, heart rate of 68 bpm, respiratory rate of 15 breaths per minute, and temperature of 98.6°F. A bladder scan now reveals a post-void residual urine volume of 100 mL, slightly higher than previous measurements but still within a manageable range. A repeat urinalysis continues to show no signs of infection or blood, maintaining the absence of acute complications such as a urinary tract infection.

Given these findings, the healthcare provider discusses with the patient the possibility of adjusting his current treatment plan to better manage his symptoms. They consider options such as modifying medication dosage or trying a different class of medication. In addition, the patient is encouraged to keep a bladder diary to track his fluid intake and urination patterns more accurately. The team schedules another follow-up appointment in two months to monitor the effectiveness of any new interventions and to ensure the patient remains comfortable and free of further complications. This proactive approach aims to address the patient's concerns while continuing to effectively manage his condition.
