redirect from views.py not works

hi all,
I have a views.py

...
def update_patient_view(request,pk):
    patient=models.Patient.objects.get(id=pk)
    user=models.User.objects.get(id=patient.user_id)
    notes=models.PatientsNotes.objects.all().filter(patient_id=patient.get_patient_id)
    visite=models.Visita.objects.all().filter(patient_id=patient.get_patient_id)

    userForm=forms.PatientUserForm(instance=user)
    patientForm=forms.PatientForm(instance=patient)
    mydict={'userForm':userForm,'patientForm':patientForm,'notes':notes,'visite':visite,'patientID':pk}

    return render(request,'hospital/admin2patient/admin_update_patient.html',context=mydict)

def add_patient_note_view(request,pk):
    ...
    if request.method=='POST':
        patientNotesForm=forms.PatientNotesForm(request.POST,instance=patientNotes)
        if patientNotesForm.is_valid():
            ...
            mydictReturn={'userForm':userForm,'patientForm':patientForm,'patientID':pk}
            return render(request,'hospital/admin2patient/admin_update_patient.html',context=mydictReturn)
           
    return render(request,'hospital/admin2patient/admin_add_patient_note.html',context=mydict)

navigating the application I obtain the following tree:
1)start from page http://127.0.0.1:8000/update-patient/1 ā†’
2)pushing button on html page (<a href="{% url 'add-patient-note' patientID %}">)
I go on page http://127.0.0.1:8000/add-patient-note/1 ā†’
3)with submit form if if patientNotesForm.is_valid(): is valid the django show me the html page of update-patient but with the url in the url bar equal to http://127.0.0.1:8000/add-patient-note/1 while I want reload http://127.0.0.1:8000/update-patient/1 reloading alla data defined in update_patient_view(request,pk):

I can not understand why the return render not works

many thanks in advance

Iā€™m sorry for disturb
I solve with

from django.urls import reverse
...
return HttpResponseRedirect(reverse('update-patient', kwargs={"pk": pk}))

I forgot include from django.urls import reverse when I tried the reverse option during all my test following some tutorial found online
