Robot-assisted Radical Cystectomy with Orthotopic Neobladder Reconstruction: Techniques and Functional Outcomes in Males

BACKGROUND

Little is known regarding functional outcomes after robot-assisted radical cystectomy (RARC) and intracorporeal neobladder (ICNB) reconstruction.

OBJECTIVE

To report on urinary continence (UC) and erectile function (EF) at 12 mo after RARC and ICNB reconstruction and investigate predictors of these outcomes.

DESIGN, SETTING, AND PARTICIPANTS

We used data from a multi-institutional database of patients who underwent RARC and ICNB reconstruction for bladder cancer.

SURGICAL PROCEDURE

The cystoprostatectomy sensu stricto followed the conventional steps. ICNB reconstruction was performed at the physician's discretion according to the Studer/Wiklund, S pouch, Gaston, vescica ileale Padovana, or Hautmann technique. The techniques are detailed in the video accompanying the article.

MEASUREMENTS

The outcomes measured were UC and EF at 12 mo.

RESULTS AND LIMITATIONS

A total of 732 male patients were identified with a median age at diagnosis of 64 yr (interquartile range 58-70). The ICNB reconstruction technique was Studer/Wiklund in 74%, S pouch in 1.5%, Gaston in 19%, vescica ileale Padovana in 1.5%, and Hautmann in 4% of cases. The 12-mo UC rate was 86% for daytime and 66% for nighttime continence, including patients who reported the use of a safety pad (20% and 32%, respectively). The 12-mo EF rate was 55%, including men who reported potency with the aid of phosphodiesterase type 5 inhibitors (24%). After adjusting for potential confounders, neobladder type was not associated with UC. Unilateral nerve-sparing (odds ratio [OR] 3.85, 95% confidence interval [CI] 1.88-7.85; p < 0.001) and bilateral nerve-sparing (OR 6.25, 95% CI 3.55-11.0; p < 0.001), were positively associated with EF, whereas age (OR 0.93, 95% CI 0.91-0.95; p < 0.001) and an American Society of Anesthesiologists score of 3 (OR 0.46, 95% CI 0.25-0.89; p < 0.02) were inversely associated with EF.

CONCLUSIONS

RARC and ICNB reconstruction are generally associated with good functional outcomes in terms of UC. EF is highly affected by the degree of nerve preservation, age, and comorbidities.

PATIENT SUMMARY

We investigated functional outcomes after robot-assisted removal of the bladder in terms of urinary continence and erectile function. We found that, in general, patients have relatively good functional outcomes at 12 months after surgery.

[When a urological emergency indicates an internal medical crisis : Priapism as the first clinical manifestation of leukemia]

Priapism as a sign of a severe hematological disease is a rare event, which has to be considered as both a urological and a hematological emergency that requires immediate treatment. This article describes a clinical case of priapism as the first clinical manifestation of a hitherto undiagnosed chronic myeloid leukemia (CML) and discusses the results of a literature review on this topic.

Implanting permanent left ventricular assist devices in patients on veno-arterial extracorporeal membrane oxygenation support

Selected patients who fail to be weaned off temporary veno-arterial extracorporeal membrane oxygenation support may be considered for long-term left ventricular assist devices.  We describe here a left ventricular assist device implantation technique in patients with prior veno-arterial extracorporeal membrane oxygenation support without the use of a cardiopulmonary bypass machine, which minimizes the intraoperative trauma and blood loss while still meeting all the goals of the standard procedure.

Rapid progressive glomerulonephritis in patients with familial Mediterranean fever

Two patients with a long-standing history of familial Mediterranean fever (FMF) presented with gross hematuria, oliguria, and acute renal failure; both required dialysis support. Kidney biopsies from both patients revealed crescentic rapid progressive glomerulonephritis (RPGN) without amyloidosis. One patient recovered renal function with methylprednisolone pulse therapy and cyclophosamide. The second patient did not improve and required regular hemodialysis. He is asymptomatic on colchicine therapy. To our knowledge, these are the first cases documenting the presence of RPGN in patients with FMF.
