Fig 1.
Flow chart of the study enrollment.
Patients were excluded if they had only an image before, image was over six months before transplantation, underwent bilateral nephrectomy before transplantation, had concurrent cyst hemorrhage, infection or abscess, were unable to perform MRI, had less than 20 mL/min of eGFR at the time of last imaging, underwent combined transplantation and underwent second transplantation.
Table 1.
Clinical data of 40 patients kidney transplant recipients.
Patients of group SKT (25 patients) were compared with group KT(15 patients).
Fig 2.
Magnetic resonance imaging of a 52 year-old woman, with end-stage renal disease due to autosomal dominant polycystic kidney disease.
Pretransplant Axial T2 weighted (A) and Coronal T2 weighted images (B) demonstrated a massive enlargement of both kidneys with the lower pole in the iliac fossa. The patient underwent a kidney transplantation with simultaneous right nephrectomy, and 1-year Axial T2 weighted (C) and Coronal T2 weighted images (D) demonstrated a significant reduction of kidney volume.
Fig 3.
Rate of change in native kidney longitudinal diameters after transplantation.
Patients with simultaneous nephrectomy and kidney transplantation were compared with patients who underwent a kidney transplant alone. Patients in both groups exhibited a statistically significant reduction of native polycystic kidney longitudinal diameters after transplantation, more pronounced in patients who underwent a simultaneous nephrectomy.
Fig 4.
Visual figure demonstrating the rate of change in native kidney longitudinal diameters after transplantation compared to pre-transplant evaluation.
The rates of change were equally statistically significant for patients who underwent simultaneous nephrectomy and kidney transplantation (A) and patients who underwent the kidney transplantation alone (B).
Table 2.
Patients with longitudinal kidney diameters decrease divided into 3 subgroups according to the rate of decrease.
In patients with different variation in size of the two kidneys, it was considered the kidney with the highest variation.
Fig 5.
Rate of change in native kidney volume after transplantation in patients with ADPKD.
Patients who did not undergo simultaneous nephrectomy displayed a highly significant reduction of kidney volume after transplantation, while patients who underwent simultaneous nephrectomy had a reduction of kidney volume, although not statistically significant.
Fig 6.
Visual figure of the rate of change of kidney volume after transplantation.
Reduction of volume was less pronounced in patient with simultaneous nephrectomy (A) compared with patients without nephrectomy (B).
Table 3.
Patients with total kidney volume decrease divided into 3 subgroups according to the degree of reduction.
In patients with different variation in size of the two kidneys, it was considered the kidney with the highest variation.
