What is the treatment plan for a patient with leukocyturia (White Blood Cell count 21-50), hematuria (Red Blood Cell count 21-30), bacteriuria (many bacteria), hemoglobinuria (trace blood), proteinuria (100 mg), and esterase-positive leukocytes, with imaging findings of mild left hydroureteronephrosis, a 3 mm ureterovesical junction (UVJ) stone, and urinary bladder wall thickening suggestive of cystitis?

From the Guidelines

The treatment plan for this patient should focus on addressing both the urinary tract infection (UTI) and the 3 mm kidney stone at the ureterovesical junction (UVJ) with empiric antibiotic therapy and supportive care. Given the presence of many bacteria, blood, and leukocytes in the urine, as well as the patient's hydroureteronephrosis and bladder wall thickening, it is crucial to initiate treatment promptly. According to the European Association of Urology guidelines on urological infections 1, fluoroquinolones and cephalosporins are recommended for oral empiric treatment of uncomplicated pyelonephritis. Therefore, I recommend starting empiric antibiotic therapy with a fluoroquinolone, such as ciprofloxacin 500 mg twice daily for 7 days, or a cephalosporin, such as cefixime 400 mg once daily for 7 days, if there are no contraindications. For pain management, ibuprofen 600 mg every 6 hours as needed is appropriate. The patient should increase fluid intake to at least 2-3 liters daily to help flush bacteria and facilitate stone passage. Given the small size of the stone (3 mm), it will likely pass spontaneously, but the patient should strain their urine to catch the stone for analysis. Follow-up urinalysis and culture should be performed 1-2 weeks after completing antibiotics to ensure resolution of the infection. If symptoms worsen, fever develops, or the stone doesn't pass within 2-4 weeks, urological consultation is warranted. The hydroureteronephrosis and bladder wall thickening are likely due to the obstructing stone and infection, respectively, and should improve with appropriate treatment of these underlying conditions. It is also important to consider the patient's overall health status and potential underlying conditions that may affect the treatment plan, as outlined in the guidelines for hematuria evaluation 1. However, in this case, the primary focus should be on treating the UTI and managing the kidney stone, with further evaluation and management of any underlying conditions as needed. The 2007 guideline for the management of ureteral calculi 1 provides additional guidance on the management of kidney stones, but the primary recommendation for a 3 mm stone at the UVJ is to allow for spontaneous passage with supportive care.

DOSAGE AND ADMINISTRATION - ADULTS Ciprofloxacin Tablets USP 250 mg, 500 mg and 750 mg should be administered orally to adults as described in the Dosage Guidelines table The determination of dosage for any particular patient must take into consideration the severity and nature of the infection, the susceptibility of the causative organism, the integrity of the patient’s host-defense mechanisms, and the status of renal function and hepatic function. Intra-Abdominal* Complicated 500 mg q 12 h 7 to 14 Days Urinary Tract Infections: The usual duration is 7 to 14 days; however, for severe and complicated infections more prolonged therapy may be required.

The patient has a complicated urinary tract infection with many bacteria, WBC urine 21-50, RBC urine 21-30, and a 3 mm stone either at or immediately adjacent to the UVJ, as well as mild left hydroureteronephrosis and urinary bladder wall thickening.

• The recommended dose for complicated urinary tract infections is 500 mg q 12 h for 7 to 14 days 2.
• The patient should be treated for at least 7 to 14 days, but more prolonged therapy may be required for severe and complicated infections.
• It is essential to consider the severity and nature of the infection, the susceptibility of the causative organism, the integrity of the patient’s host-defense mechanisms, and the status of renal function and hepatic function when determining the dosage.
• The patient's renal function should be taken into account, as ciprofloxacin is eliminated primarily by renal excretion.
• The treatment plan should be adjusted according to the patient's response to the therapy and the duration of treatment depends upon the severity of infection.

From the Research

Treatment Plan

The patient's urinalysis results show WBC urine 21-50, RBC urine 21-30, bacteria many, blood trace, protein urine 100, and leukocytes est small. The CT abdomen and pelvis results indicate mild left hydroureteronephrosis to the level of the UVJ, a 3 mm stone either at or immediately adjacent to the UVJ, and urinary bladder wall thickening, which may be correlated with cystitis.

Antibiotic Treatment Options

• Ciprofloxacin extended release may be considered as a treatment option for urinary tract infections (UTIs) 3, 4, 5.
• Amoxicillin/clavulanate may be a useful alternative therapy for the treatment of ceftriaxone non-susceptible Enterobacterales UTIs 6.
• The choice of antibiotic should be based on the severity of the infection, the presence of any underlying medical conditions, and the patient's allergy history.

Considerations

• The patient's UTI may be caused by a Gram-negative organism, and the rise of resistant isolates should be considered when selecting an antibiotic 6.
• The patient's kidney stone and hydroureteronephrosis may require additional treatment, such as pain management and hydration.
• The patient's cystitis may require additional treatment, such as urinary analgesics and increased fluid intake.

Potential Outcomes

• Effective treatment of the UTI with antibiotics, such as ciprofloxacin or amoxicillin/clavulanate, may lead to clinical cure and bacteriological eradication 3, 6, 5.
• Failure to treat the UTI effectively may lead to complications, such as pyelonephritis or sepsis.
• The patient's kidney stone and hydroureteronephrosis may require surgical intervention if they do not respond to conservative treatment.
