Suspicious adrenal incidentaloma in a patient with Congenital Adrenal Hyperplasia: A case report

Congenital Adrenal Hyperplasia has been associated with an increased prevalence of adrenal masses. It is still unknown whether incidentalomas in CAH* patients are more frequent or if the risk of adrenal carcinoma is higher than the general population. Therefore, the management CAH subjects presenting with suspicious adrenal masses remains problematic.

We relate the case of a patient with CAH presenting for an adrenal incidentaloma with malignant features. The management of such cases is controversial as surgery is risky for large masses. Despite dimensions, a laparoscopic approach was used for resection. The patient remained disease free at 4 years post-operatively.

First live birth after uterus transplantation in the Middle East

Background

The first live birth after uterus transplantation took place in Sweden in 2014. It was the first ever cure for absolute uterine factor infertility. We report the surgery, assisted reproduction, and pregnancy behind the first live birth after uterus transplantation in the Middle East, North Africa, and Turkey (MENAT) region.

A 24-year old woman with congenital absence of the uterus underwent transplantation of the uterus donated by her 50-year-old multiparous mother. In vitro fertilization was performed to cryopreserve embryos. Both graft retrieval and transplantation were performed by laparotomy. Donor surgery included isolation of the uterus, together with major uterine arteries and veins on segments of the internal iliac vessels bilaterally, the round ligaments, and the sacrouterine ligaments, as well as with bladder peritoneum. Recipient surgery included preparation of the vaginal vault, end-to-side anastomosis to the external iliac arteries and veins on each side, and then fixation of the uterus.

Results

One in vitro fertilization cycle prior to transplantation resulted in 11 cryopreserved embryos. Surgical time of the donor was 608 min, and blood loss was 900 mL. Cold ischemia time was 85 min. Recipient surgical time was 363 min, and blood loss was 700 mL. Anastomosis time was 105 min. Hospital stay was 7 days for both patients. Ten months after the transplantation, one previously cryopreserved blastocyst was transferred which resulted in viable pregnancy, which proceeded normally (except for one episode of minor vaginal bleeding in the 1st trimester) until cesarean section at 35 + 1 weeks due to premature contractions and shortened cervix. A healthy girl (Apgar 9-10-10) weighing 2620 g was born in January 2020, and her development has been normal during the first 6 months.

Conclusions

This is the first report of a healthy live birth after uterus transplantation in the MENAT region. We hope that this will motivate further progress and additional clinical trials in this area in the Middle East Region, where the first uterus transplantation attempt ever, however unsuccessful, was performed already three decades ago.

Decrease in and management of urolithiasis after kidney transplantation

PURPOSE

Urolithiasis after kidney transplantation can involve several contributing factors and the treatment strategy is open to question. We determined the incidence and management of urolithiasis in kidney recipients.

MATERIALS AND METHODS

We retrospectively reviewed a single center series of 3,000 kidney graft recipients during 32 years to identify those with urolithiasis. We analyzed data by the prevalence per decade, including perioperative procedures (preoperative assessment, anastomosis type and urinary drainage) and long-term followup (urinary stenosis, time to presentation, size, site, treatment type, renal function and survival).

RESULTS

We identified 31 cases and noted a significant decrease in incidence from 2.1% to 0.6% during the 3 decades. Excluding 4 cases of donor in situ stones the mean time to diagnosis was 8.5 years. Surgical risk factors were ureteral obstruction in 41% of cases, infravesical obstruction in 14% and urinary-digestive anastomosis in 14%. A total of 12 cases (38%) were observed exclusively with 2 of spontaneous passage. With minor adaptations all mini-invasive procedures, including extracorporeal shock wave lithotripsy, endoscopy and percutaneous nephrolithotomy, were feasible in graft recipients. Antegrade procedures were facilitated by the ventral position of the graft. Eight patients (25%) were treated with open surgical ureteroureteral anastomosis.

CONCLUSIONS

Prevention with a perioperative Double-J® stent and early treatment of ureteral obstruction have decreased and stabilized the urolithiasis rate at around 0.6%. Careful surveillance or any currently available instrumental treatments of urinary stones can be valid options.

Prevalence of renal cell carcinoma in patients with autosomal dominant polycystic kidney disease and chronic renal failure

OBJECTIVES

To study the prevalence and the characteristics of renal cell carcinoma (RCC) in patients with autosomal dominant polycystic kidney disease (ADPKD) in our series.

METHODS

We reviewed retrospectively all the nephrectomies performed in our department between 1982 and 2003 in patients with ADPKD and chronic renal failure.

RESULTS

Seventy-nine patients (42 males and 37 females) with ADPKD and chronic renal failure underwent 89 nephrectomies; in 10 of 79, both kidneys were removed but not simultaneously. Mean age was 50.4 years (range, 32-69 years). Of 79 patients, 50 had end-stage renal disease (ESRD) and were on hemodialysis or had received a transplant for >1 year. On histologic examination, 11 of 89 kidneys were diagnosed with carcinomas. There was 1 patient with bilateral tumor (tubulopapillary Ca) and 3 kidneys (27.3%) with multifocal tumors. Regarding the histologic type, there were 7 of 12 (58.3%) clear cell carcinomas and the remaining 5 (41.7%) were tubulopapillary carcinomas.

CONCLUSIONS

The prevalence of RCC was higher in patients with ADPKD and ESRD, with >1 year on dialysis or renal transplantation undergoing nephrectomy according the protocol. It would be 2 to 3 times more frequent than RCC in patients with ESRD alone. The clinician should maintain a high alert of suspicion for RCC in such patients.

[A case of ureteroduodenal fistula]

Ureteroduodenal fistulas are rare. The authors present a review of this disease in the light of a clinical case and emphasize the role of conservative management.
