Lymphatic network of kidney. I. Anatomic and physiologic considerations

Area of Science:

• Nephrology
• Immunology
• Pharmacology

Background:

• Decades of research on kidney lymphatics have yielded significant data, often published in specialized journals.
• A need exists to consolidate and organize these findings for broader accessibility.

Purpose of the Study:

• To present organized concepts regarding kidney lymphatics and ignored physiologic principles.
• To highlight the role of immunoblasts in renal allograft rejection.
• To discuss the importance of antibiotic concentrations in renal tissue for treating pyelonephritis.

Main Methods:

• Review of existing literature on kidney lymphatics.
• Evaluation of fourteen antibacterials in mongrel dogs, comparing plasma, urine, and renal lymph levels.
• Analysis of diuretic effects on renal tubular reabsorption and interstitial solute gradients.

Main Results:

• Kidney lymph contains immunoblasts crucial for renal allograft rejection.
• Early and adequate dosage of Azathioprine (Imuran) can mitigate the role of transformed lymphocytes.
• Renal tissue concentrations of antibacterials are critical for eradicating acute pyelonephritis, potentially more so than blood or urine levels.

Conclusions:

• Organized reviews are necessary to disseminate key findings on kidney lymphatics.
• Understanding renal lymph and its components, like immunoblasts, is vital for transplantation and infection treatment.
• Antibiotic and diuretic strategies should consider renal lymph dynamics for optimal therapeutic outcomes.
