  • To describe the principles of measurement of glomerular filtration rate and renal blood flow
  • To describe the physiological effects and clinical assessment of renal dysfunction
  • To explain the renal responses to hypovolaemia
  • To cognise the interaction with the cardiovascular and respiratory system for the homeostasis of the extracellular fluid and blood pressure regulation
  • To be able to perform simple biochemical tests and to interpret the results.
  • To be able to discuss general principles of major and most frequently occurring pathologies of the urinary system together with basics in their diagnosis paths and treatments.
  • To comprehend the role of kidneys in the metabolism, catabolism and elimination of drugs and medicines.

Learning outcomes will be achieved through adoption of theoretical knowledge and training in different skills, with particular emphasis on case studies (PBL - Problem Based Learning).

1.1.Concept of the external and internal environment
1.2.Exchanges between compartments
1.3.Hemodynamic
1.4.Regulation of volume and osmolarity of body fluids
Aquaporins, Na+/K+-ATPase, regulation via AVP/ADH, regulation via PTH, Vitamin D
1.5.Renin-Angiotensin-Aldosterone system
2.Elements of the renal physiology
2.1.Essential functions
2.2.Functional anatomy of the kidney
2.3.Glomerular filtration
2.4.Tubular systems
2.5.Regulation of the renal system
3. Acid-base homeostasis
3.1 Concept of physiological pH and acid balance - weak bases
3.2 Functional basis of pH controlby the lung and the kidney
Biochemistry / Prof Iris Behrmann / Normal functions:
(will be matched with the corresponding Physiology courses)
-Excretion of metabolic end products
-Regulation of the acid/base balance (pH equilibrium)
proton transporters, glutamine degradation -> ammonium excretion
-Endocrine functions
Erythropoietin (specific aspect: Hypoxia signaling leading to Epo gene expression),
- Specific aspects of the metabolism in different parts of the nephron (energy metabolism, Vitamin D, catabolism of filtrated proteins)
(will be matched with the corresponding Anatomy / Cell Biology courses)
- Urine: “normal” composition
(+ pregnancy test: hCG content of urine)
Pharmacology
(broad principles only) / Prof Eric Tschirhart /
  1. Antibiotics used in treatment of urinary infections caused by most common pathogens
  2. Antibiotic resistance
  3. Initiation into a kidney stones treatment
  4. Initiation into treatment of most frequently occuring kidney carcinoma
  5. The role of kidneys in metabolism, catabolism and elimination of drugs or medicines.

Manual, therapeutic and diagnostic competencies:

By the end of the module:

  • the student will know which questions to address to the patient during history taking in order to explore or exclude potential pathologies of the urinary system
  • The student will be able to explain to the patient how to take a urine sample
  • The student will be able to perform a physical observation of urine, to do a dipstick examination and to interpret the results. He/she will know when to request the bacteriological cultivation of the sample
  • The student will become familiar with the treatment used for the most common urinary infections, kidney stones and most frequently occurring carcinoma of kidney

It is expected that the student undertakes 2 ward rounds at the kidney ward during the module (midterm and end of a module round).

Scientific competencies(E.g. Literature research on success of different therapiesin treatment of urinary infections with respect to the cause of infection. Research to be concluded with a short report.)

Social and communicative competences(E.g. Basics of doctor-patientapproach mainly through peer to peer exercises. By the end of the module student will be able to showbasic skills in appropriately balancing distance and proximity to the patient with adequate level of emotional involvement when e.g. history taking. He/she will be able to enquire respectfully and without judgmentabout patient`s social and family context). He/she will demonstrate clear history taking and its clear reporting to the supervisor.

Human and society (Ethics and stigmatization, e.g. urinary incontinence)

2. Means of teaching-learning processare:

  • direct contact lectures,
  • e-learning methods,
  • assignments,
  • practical work, SkillLab
  • ward rounds,
  • cases/PBL – once per week (e.g.)
  • 20 years old female with urinary infection,
  • 60 years old male with urinary infection,
  • 70 years old male with kidney stone or cancer

Presentation of a case in the class if followed with the discussion on hypothetical diagnosis with suggestions of a treatment. Students are directed to readings.Students` self-study period will be followed by revision of the case.
