Potter syndrome causes what anomaly
bilateral renal agenesis
prognosis bilateral renal agenesis
no survival long after birth
presentation symptoms of unilateral renal agenesis
asymptomatic unless patho of kidney
supernumerary kidney has a risk of
htn
renal aplasia
kidney failed to develop beyond primitive form, incompatible w/ life if bilateral → HTN
renal hypoplasia
incomplete dev of kidney but normal dev of ureter, diminished or absent kidney fxn
treatment of renal hypoplasia
nephrectomy if HTN
renal hyperplasia
enlarged v with normal structure and increased fxnal capacity, associated w/ agenesis/hypoplasia of other kidney
indications for surgery of solitary renal cyst
cyst infection, hemorrhagic cyst, compression
ARPKD vs ADPKD
AD - symptoms bw 30 and 40
AR - symptoms after birth
cause PKD
deficiency of dev of collector tubes
PKD symptoms
pain, htn, hematuria, stones, UTI, KF
lab results PKD
increased urea and creatinine, anemia, less urine density
pos diagnosis PKD
genetic mutation, enlarged nonregular surfaced kidney, signs, imaging
prevention of pkd with diet
low salt or protein, more water
surgical treatment pkd
bilateral nephrectomy and renal transplant, dialysis
horsehoe kidney
2 renal masses united at inf pole, kidney is lower, ureters cross isthmus, abnormal vasc, renal pelvis faces ant
presentation horseshoe kidney
asymptomatic but susceptible to complications - utis, stones, hydronephrosis

intrinsic obstruction by maldev, aberrant vessels crosses jxn
effects of ureteropelvic jxn syndrome
hydronephrosis
surgery for ureteropelvic jxn syndrome
laparoscopic pyeloplasty
complications laparoscopic pyeloplasty for ureteropelvic jxn syndrome
bleeding, injury, seroma/hematomas, urinary fistulas
treatment for ureter stenosis at UPJ w/ hydronephrosis
pyeloplasty
treatment ureter stenosi at jxn
incision ureter, re-implantation
causes megaureter
obstruction (stenosis), bladder ureter reflux
ureterocele
cystic dilatation of terminal part of ureter
symptoms ureterocele
asymptomatic or utis, hematuria, lithiasis
IVU for ureterocele shows
